《Metathesis of norbornene-derivatives bearing trimethylsilyl groups using Ru-alkylidene catalysts: An experimental and computational study》 was written by Zarate-Saldana, Daniel; Landeros-Rivera, Bruno; Cruz-Morales, Jorge A.; Gutierrez, Selena. Safety of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium And the article was included in Journal of Organometallic Chemistry in 2020. The article conveys some information:

The monomer synthesis and ring-opening metathesis polymerization (ROMP) of cis-5-norbornene-exo-2,3-dicarboxylic anhydride (1a) and 7-syn-trimethylsilyl-cis-5-norbornene-exo-2,3-dicarboxylic anhydride (1b) mediated by ruthenium-alkylidene catalysts (I, II and III) were exptl. carried out. Metathesis reaction pathways of 1a and 1b monomers using II have been studied at PBE-D3(BJ)/def2-TZVP level of theory, employing the SMD model for simulation of 1,2-dichloroethane solvent. The calculations unravel that reactivity difference between 1a and 1b towards ruthenium alkylidene complex II is due to the fact that the intermediate π-complex formation was found in the 1a reaction pathway but was absent in the 1b one. Moreover, there are marked differences in the formation processes of the metallacyclobutane intermediaries 5a and 5b, the first is an exergonic process (-8.3 kcal/mol) and the last one is an endergonic process (2 kcal/mol), in addition to the high activation energy of the monomer 1b (15.8 kcal/mol) compared with 1a (5.5 kcal/mol). Such differences are attributed to the high steric impediment imposed by -Si(CH3)3 over the double bond (syn conformation). Using quantum theory of atoms in mols. (QTAIM) it was possible to analyze successfully the mechanistic pathway of metathesis reaction for both monomers, complementing the results obtained by DFT energetic anal. After reading the article, we found that the author used Benzylidenebis(tricyclohexylphosphine)dichlororuthenium(cas: 172222-30-9Safety of Benzylidenebis(tricyclohexylphosphine)dichlororuthenium)

He, Xianglong; Gao, Yanjing; Nie, Jun; Sun, Fang published an article in 2021. The article was titled 《Methyl Benzoylformate Derivative Norrish Type I Photoinitiators for Deep-Layer Photocuring under Near-UV or Visible LED》, and you may find the article in Macromolecules (Washington, DC, United States).Formula: C3H3ClO3 The information in the text is summarized as follows:

We designed and prepared a series of Me benzoylformate (MBF) derivatives Norrish type I photoinitiators (MBFs) for light-emitting diode (LED)-induced photopolymerization through computer simulation. The potential photolysis mechanism of MBFs under LED at 405 nm was explored by steady-state photolysis, NMR, and ESR. The as-synthesized photoinitiator di-Me 1,4-dibenzoylformate (DM-BD-F) can efficiently initiate free radical photopolymerization of acrylate monomers under LED irradiation at 405 nm. Moreover, we predicted well the photoinitiating capability of MBFs through the cleavage exothermy (ΔH) calculated by triplet bond dissociation energy (BDE) and triplet energy (ET). Significantly, based on the weak absorption of MBFs at 405 nm, MBFs were successfully applied to deep-layer photocuring and the curing depth reached 6.5 cm after the irradiation of LED at 405 nm for 30 s. This research provides a new idea and efficient strategy for the mol. design of photoinitiators for deep-layer photocuring. In the experimental materials used by the author, we found Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3Formula: C3H3ClO3)

Methyl 2-chloro-2-oxoacetate(cas: 5781-53-3) belongs to acyl chlorides. Lacking the ability to form hydrogen bonds, acyl chlorides have lower boiling and melting points than similar carboxylic acids. For example, acetic acid boils at 118 °C, whereas acetyl chloride boils at 51 °C. Like most carbonyl compounds, infrared spectroscopy reveals a band near 1750 cm−1.Formula: C3H3ClO3

The article conveys some information:

A review. Soil salinization is one of the major environmental stressors hampering the growth and yield of crops all over the world. A wide spectrum of physiol. and biochem. alterations of plants are induced by salinity, which causes lowered water potential in the soil solution, ionic disequilibrium, specific ion effects, and a higher accumulation of reactive oxygen species (ROS). For many years, numerous investigations have been made into salinity stresses and attempts to minimize the losses of plant productivity, including the effects of phytohormones, osmoprotectants, antioxidants, polyamines, and trace elements. One of the protectants, selenium (Se), has been found to be effective in improving growth and inducing tolerance against excessive soil salinity. However, the in-depth mechanisms of Se-induced salinity tolerance are still unclear. This review refines the knowledge involved in Se-mediated improvements of plant growth when subjected to salinity and suggests future perspectives as well as several research limitations in this field. In the experiment, the researchers used Sodium chloride(cas: 7647-14-5SDS of cas: 7647-14-5)

Related Products of 622-95-7This research focused ontriazole preparation green chem; benzyl bromide epoxide azide phenylacetylene multicomponent click reaction; surfactant free copper sulfide nano micro flower catalyst. The article conveys some information:

The copper sulfide (sf-CuS) nano/micro particles without having organic surfactant mols. as the capping agent is synthesized. These particles with a flower-like architecture (micro flowers, mf) were obtained readily under the supersaturated condition at room temperature In these particles, the surface was freely available for adsorption and desorption reactions. When utilized as a catalyst in multicomponent cycloaddition reactions, the sf-CuS mf exhibited excellent catalytic activity compared with some other nanoparticles with surfactants. This sf-CuS mf catalyzed the one-pot synthesis of 1,2,3-triazole and β-hydroxy-1,2,3-triazole effectively from a variety of benzyl bromide derivatives and epoxides resp. Both these reactions proceeded in the presence of azide and phenylacetylene in the water at room temperature The catalyst was reusable, and there was no catalyst leaching observed during reactions. Synthesis of β-hydroxy triazoles and 1,2,3-triazoles under exceptionally mild conditions with high yields proved the sf-CuS mf as the robust and recyclable catalyst.

During the studies towards synthesis of carboxylic acids esters, using Et carbonate and carboxylic acid as substrates, we found that different single enzyme systems provide model Et 3-phenylpropanoate in very low yield. Systematic studies proved that combination of two or more enzymes enhances yield of reaction. Application of selected enzyme mixture for enzymic esterification of various carboxylic acids provided resp. esters in excellent yields. Unexpectedly, the same reaction performed with mixture of five enzymes proceeds in almost quant. yield. For racemic substrates reaction catalyzed by enzyme mixture was enantioselective. To the best of our knowledge it is the very first evidence of cooperation between multiple enzymes in organic solvents.

Computed Properties of C11H13ClO2On March 7, 2022, Calogero, Francesco; Potenti, Simone; Bassan, Elena; Fermi, Andrea; Gualandi, Andrea; Monaldi, Jacopo; Dereli, Busra; Maity, Bholanath; Cavallo, Luigi; Ceroni, Paola; Giorgio Cozzi, Pier published an article in Angewandte Chemie, International Edition. The article was 《Nickel-Mediated Enantioselective Photoredox Allylation of Aldehydes with Visible Light》. The article mentions the following:

Here a practical, highly enantioselective photoredox allylation of aldehydes mediated by chiral nickel complexes with com. available allyl acetate as the allylating agent was reported. The methodol. allowed the clean stereoselective allylation of aldehydes in good to excellent yields and up to 93% e.e. using a catalytic amount of NiCl2(glyme) in the presence of the chiral aminoindanol-derived bis(oxazoline) as the chiral ligand. The photoredox system was constituted by the organic dye 3DPAFIPN and a Hantzsch’s ester as the sacrificial reductant. The reaction proceeded under visible-light irradiation Compared to other published procedures, no metal reductants (such as Zn or Mn), additives (e.g. CuI) or air-sensitive Ni(COD)2 were necessary for this reaction. Accurate DFT calculations and photophys. experiments had clarified the mechanistic picture of this stereoselective allylation reaction. After reading the article, we found that the author used Ethyl 3-(4-chlorophenyl)propanoate(cas: 7116-36-1Computed Properties of C11H13ClO2)

Ethyl 3-(4-chlorophenyl)propanoate(cas: 7116-36-1) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light.
