Ylide-functionalized phosphine ligands (YPhos) were rationally designed to fit the requirements of Buchwald-Hartwig aminations at room temperature. This ligand class combines a strong electron-donating ability comparable to NHC ligands with high steric demand similar to biaryl phosphines. The active Pd species are stabilized by agostic C-H center dot center dot center dot Pd rather than by Pd-arene interactions. The practical advantage of YPhos ligands arises from their easy and scalable synthesis from widely available, inexpensive starting materials. Benchmark studies showed that YPhos-Pd complexes are superior to the best-known phosphine ligands in room-temperature aminations of aryl chlorides. The utility of the catalysts was demonstrated by the synthesis of various arylamines in high yields within short reaction times.

High-temperature thermal energy storage in shallow aquifers can potentially increase ambient groundwater temperatures up to 70 degrees C or even more. Since an increase in temperature is expected to influence contaminant mass flux into groundwater monitoring the spreading of organic contaminants located in the subsurface is crucial. In numerous former studies, the NAPL solubility, one major parameter controlling mass flux on field scale, was measured at temperatures up to 70 degrees C for a broad spectrum of organic substances. However, quantitative calculations of solubilities as a function of temperature considering a compiled database are largely missing. Aiming to examine the reliability of existing solubility-temperature relationships, to describe them functionally and further to identify knowledge gaps, previously published data on solubilities of 42 different organic groundwater contaminants were evaluated in this study. By using a common temperature regression function, the calculated solubility curves from compiled solubility data for 5-70 degrees C show relative changes between a few percent (CHCs and BTEX) and up to 2000% (PAH5). As published temperature-dependent solubilities for chlorinated ethylenes are contradictory in parts, solubilities of tetrachloroethylene, trichloroethylene, 1,2-cis-dichloroethylene and 1,2-trans-dichloroethylene were additionally investigated in more detail using batch experiments between 5 and 70 degrees C. The results show distinctive solubility minima at medium temperatures (20-40 degrees C) with concentrations decreasing from 5 degrees C to the minimum by 10-20%. The measured and calculated temperature-dependent solubilities enable a more reliable assessment of thermal energy storage at contaminated sites, of existing thermal remediation approaches and of combinations of underground heat storage with groundwater remediation.

Potable reuse facilities must be designed and operated to minimize the presence of contaminants of emerging concern (CECs) and other trace organics in the product water. Reverse osmosis (RO) is incorporated into the process train of many potable reuse facilities and has been demonstrated to achieve excellent removal of many, but not all, organic compounds. Organics that may be poorly removed by RO include low-molecular weight (MW) neutral compounds. This laboratory study examined the rejection of 73 low-MW neutral organics through a commercial RO membrane that is commonly used in potable reuse applications. The organics were selected using a reductionist approach so that the effect of individual functional groups on rejection could be ascertained. The research demonstrated that halogens, carbonyl functional groups, C=C double bonds, and aromaticity decrease rejection, that methyl and hydroxyl functional groups increase rejection, and that the position of functional groups in structural isomers has a significant effect on rejection. The results help explain the discrepancies and inconsistencies in RO rejection of neutral organics that are observed when considered from the conventional perspective of molecular size and hydrophobicity.

A concurrent tandem catalytic (CTC) methodology has been developed for the amidation of aryl chlorides where the aryl chloride is first converted to an aryl iodide via halogen exchange and the aryl iodide is subsequently transformed into the aryl amide. A variety of aryl chlorides were converted to aryl amides in up to 85% isolated yield using 20 mol % CuI, 60 mol % N,N’-cyclohexane-1,2-diamine, 2.2 equiv of K2CO3, and 1.05-1.5 equiv of amide in acetonitrile at 200 degrees C after 0.75-1 h. The same copper/ligand system served as multifunctional catalyst for both steps of the concurrent catalytic process with iodide present in substoichiometric amounts. Mechanistic studies were consistent with CTC amidation occurring via a nonradical mechanism. Kinetic modeling was conducted to investigate the effect of competitive direct amidation of an aryl chloride or aryl bromide on the formation of product over time during a CTC amidation reaction.

Herein we disclosed the utilization of copper loaded zinc oxide (ZnO-Cu) for its stimuli (O-2/light) responsive switchable performance between its reduced (S-1) and oxidized (S-2) state for two antagonistic reactions, namely oxidation of alkyl arenes/heteroarenes to aldehydes/ketones and reduction of nitro arenes/heteroarenes corresponding amines. The two states of the catalyst showed its switchable performance as highly active and poorly active catalyst for oxidation and reduction, and both reactions could be turned off and on by changing the stimuli (light and O-2/N-2). The switching efficiency between the states and their relative reactivity were found to be consistent under variety of reaction conditions and remain unaltered irrespective of oxidation-reduction (or vice versa) sequence and substrates used in the reaction. The photo catalysts (S-1 and S-2) demonstrated good catalytic activity, multiple reusability, broad substrate scope, and reasonable functional group tolerance for both the reactions and probed its quality performance in a large-scale setup. The system was used in an assisted tandem catalysis setup for the synthesis of benzyl amines utilizing both oxidation and reduction reaction by stimuli responsive switching between the states of the catalyst.

Structural modifications of nicotinamide, a form of vitamin B3, gave rise to a series of compounds (8aa-8ce) that exhibit activities as type I positive allosteric modulators (PAMs) of human alpha 7 nAChR expressed in Xenopus oocytes in two-electrode voltage clamp assay. The compound 8ai was a potent and efficacious PAM with an EC50 = 3.34 +/- 1.13 mu M and the maximum activation effect of alpha 7 current over 1474 +/- 246% in the presence of acetylcholine (100 mu M). It is highly specific to alpha 7 nAChR over other subtypes of nAChR and 5-HT3A receptors. The structure-activity relationship analysis identified a key skeleton of nicotinamide nucleus critical for biological activity. Taken together, the 8ai as a type I PAM of alpha 7 nAChR may be beneficial for improvement of cognitive deficit.

Recommanded Product: 95-49-8. I found the field of Chemistry very interesting. Saw the article Nickel-Catalyzed Hydroarylation of Alkynes under Reductive Conditions with Aryl Bromides and Water published in 2019, Reprint Addresses Wilger, DJ (corresponding author), Samford Univ, Dept Chem & Biochem, Birmingham, AL 35229 USA.. The CAS is 95-49-8. Through research, I have a further understanding and discovery of 1-Chloro-2-methylbenzene.

An operationally simple nickel-catalyzed hydroarylation reaction for alkynes is described. This three component coupling reaction utilizes commercially available alkynes and aryl bromides, along with water and Zn. An air-stable and easily synthesized Ni(II) precatalyst is the only entity used in the reaction that is not commercially available. This reductive cross-coupling reaction displays a fairly unusual anti selectivity when aryl bromides with ortho substituents are used. In addition to optimization data and a preliminary substrate scope, complementary experiments including deuterium labeling studies are used to provide a tentative catalytic mechanism. We believe this report should inspire and inform other Ni-catalyzed carbofunctionalization reactions.

A photo-induced atom transfer radical addition (ATRA) of aryl chlorides onto alkenes has been developed in the synthesis of chloroalkyl benzenes, in which chlorine radicals and aryl radicals can be generated simultaneously at ambient temperature without the involvement of any initiator or catalyst. The inherently reactive and energetic chlorine radicals also benefit a photo-induced aminocarbonylation reaction of aryl chlorides with carbon monoxide and amines via a hydrogen-abstraction step. These two reactions can provide an inspiration for organic reaction with a radical-designed process. Finally, a photo-induced multi-phase reaction system is extended to flow mode to yield scaled-up products on a gram scale.

Protein kinases play a crucial role in many cell signaling processes, making them one of the most important families of drug targets. In this context, fragment-based drug design strategies have been successfully applied to develop novel kinase inhibitors. These strategies usually follow a knowledge-driven approach to optimize a focused set of fragments to a potent kinase inhibitor. Alternatively, KinFragLib explores and extends the chemical space of kinase inhibitors using data-driven fragmentation and recombination. The method builds on available structural kinome data from the KLIFS database for over 2500 kinase DFG-in structures cocrystallized with noncovalent kinase ligands. The computational fragmentation method splits the ligands into fragments with respect to their 3D proximity to six predefined functionally relevant subpocket centers. The resulting fragment library consists of six subpocket pools with over 7000 fragments, available at https://github.com/volkamerlab/KinFragLib. KinFragLib offers two main applications: on the one hand, in-depth analyses of the chemical space of known kinase inhibitors, subpocket characteristics, and connections, and on the other hand, subpocket-informed recombination of fragments to generate potential novel inhibitors. The latter showed that recombining only a subset of 624 representative fragments generated 6.7 million molecules. This combinatorial library contains, besides some known kinase inhibitors, more than 99% novel chemical matter compared to ChEMBL and 63% molecules compliant with Lipinski’s rule of five.
