Alternatives to the use of pressurized hydrogen (H-2) in chemical syntheses are of growing interest and importance in developing safer protocols. Ammonia borane (AB), with its high hydrogen content and ability to release H-2 under mild conditions, is one potential solution. However, optimization of AB dehydrogenation and further the use of AB as a H-2 source to facilitate tandem one-pot reactions with both high activity and stability is an ongoing research challenge. In this work, monodisperse AuPd nanoparticle (NP) catalysts were synthesized and systematically studied for AB dehydrogenation, and Au-rich NPs were found to be the most active composition for AB methanolysis with a turnover frequency (TOF) of 160 min(-1) surpassing most Pd-based NP catalysts to date. More importantly, Au-rich NPs were also active in the one-pot tandem reduction of a series of nitro-groups and the hydrodehalogenation of mono- and polyhalogenated persistent chemical pollutants under mild reaction conditions using only a 2:1 molar ratio of AB to substrate. The AuPd catalyst was stable after ten reaction runs for AB methanolysis and five reaction runs for tandem one-pot reactions without a loss of activity or change in NP structure and morphology.

An efficient, metal-free C-H halogenated method for the synthesis of beta-halogenated carboxamides using non-corrosive NXS (X=Cl, Br) as the halogenated source and ammonium sulfocyanide (NH4SCN) as the additive was proposed and accomplished. Various substituted 2-oxazolines efficiently afforded the corresponding beta-halogenated carboxamides via a ring-opening reaction in good yields. The characteristic features of this reaction include readily available materials, mild reaction conditions and functional groups tolerance.

A novel oxidative esterification of 1-arylprop-2-en-1-ols with toluene derivatives catalyzed by tetrabutylammonium iodide (TBAI) is reported. The optimization of the reaction conditions illustrates that each of experiment parameters including the catalyst, solvent, and oxidant is significant for present oxidative functionalization. This metal-free protocol has a broad substrate scope including the halogen groups for further functionalization and enriches the reactivity profile of allyl alcohol and toluene derivatives. In addition, this protocol represents a new transformation of allyl alcohol involving C-C bond cleavage and C-O bond forming.

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 green and efficient method for the synthesis of amides has been developed through oxidative amidation between methylarenes with amines in a two-step continuous flow system. This method integrates methylarene oxidation and amide formation into a single operation which is usually accomplished separately. Oxidation with tert-butyl hydroperoxide (TBHP) as green oxidant, the synthesis of amides under mild reaction conditions in continuous flow system and the utilization of methylarenes as starting material make this methodology novel and environment friendly. The practical value of this method is highlighted through the synthesis of high-profile pharmaceutical agents, acetylprocainamide. (C) 2020 Elsevier Ltd. All rights reserved.

The challenging nickel-catalyzed mono-alpha-arylation of acetone with aryl chlorides, pivalates, and carbamates has been achieved for the first time. A nickel/Josiphos-based catalytic system is shown to feature unique catalytic behavior, allowing the highly selective formation of the desired mono-alpha-arylated acetone. The developed methodology was applied to a variety of (hetero)aryl chlorides including biologically relevant derivatives. The methodology has been extended to the unprecedented coupling of acetone with phenol derivatives. Mechanistic studies allowed the isolation and characterization of key Ni(0)and Ni(II)catalytic intermediates. The Josiphos ligand is shown to play a key role in the stabilization of Ni(II)intermediates to allow a Ni-0/Ni(II)catalytic pathway. Mechanistic understanding was then leveraged to improve the protocol using an air-stable Ni(II)pre-catalyst.

A novel third-nonlinear optical (NLO) crystal, piperazine-1,4-diium bis(2,4-dichlorobenzoate) (abbreviated as PBDCB) was successfully synthesized and grown good quality crystal by slow evaporation solution growth technique by methanol as a solvent at room temperature. The formation of the grown crystal was carried out by single-crystal X-ray diffraction analysis. The analysis of a single crystal X-ray diffraction reveals that the title compound was crystallized in the monoclinic system with centrosymmetric space group P21/c and thereof lattice parameter are a = 11.166(6) angstrom, b = 8.160(5) angstrom, c = 12.085(6) angstrom, beta= 113.18(3) degrees, Z = 4. Crystallographic studies also reveal that the molecules are linked via N-HO and C-H Cl hydrogen bonds. Pairs of intermolecular N-HO hydrogen bonds generate R 4 4 (12) ring motifs. The powder X-ray diffraction study was completed and the peaks were indexed. UV-Vis spectral studies were revealed that the grown crystal is transparent in the entire visible region with a lower cut off the wavelength of 286 nm. The optical band gap of the title compound was measured by Tauc’s plot method, and it was obtained to be 3.9 eV, which shows suitable applications of the optoelectronic device. In the photoluminescence study, the grown crystal was revealed violet emission radiation, and thereof peak has appeared at 312 nm. The functional groups of the grown crystal have been determined by Fourier Transform Infra-Red (FTIR) spectroscopy technique. In thermogravimetric (TGA) and differential thermal analysis (DTA) analysis, the title material was determined as thermally as stable up to 163 degrees C. The Vickers Microhardness test ascertained the mechanical properties of the grown crystal material, and it belongs to a soft material category. The dielectric measurements of the developed crystal material were also ascertained at various frequencies. The dielectric constant, dielectric loss, and A.C. the conductivity of title material was studied with different frequencies and temperatures. The laser damage threshold (LDT) of the grown crystal was then calculated by using Nd: YAG laser. The grown crystal has given the measured (LDT) value of 8.97 GW/cm2. The third-order nonlinear optical (NLO) properties characteristics, such as absorption coefficient (beta similar to 0.02 x 10 -4 cm/W), the refractive index (n(2) similar to 4.06 x 10(-8) cm(2)/W), and their susceptibility range values of (chi((3)) similar to 2.17 x 10(-6)esu) of the grown crystal was estimated by Z-scan technique, suggests that the grown crystal material PBDCB was served as a promising source for nonlinear optical devices.
