Design and synthesis of base-metal nickel(II) based catalysts: studies on nearly selective formation of 1-butene from ethylene

A new family of base-metal nickel complexes [Ni(L1-10)(2)] (1-10) were synthesized from tridentate meridional ligands (LH)-H-1 to (LH)-H-10 (where H stands for dissociable proton). Different spectroscopic studies were utilized for the characterization of these complexes [Ni(L1-10)(2)] (1-10). Molecular structures of complexes [Ni(L-1)(2)] (1), [Ni(L-3)(2)] (3) and [Ni(L-8)(2)] (8) were determined by X-ray crystallography. Electronic properties of complexes [Ni(L-1)(2)] (1) [Ni(L-3)(2)] (3) and [Ni(L-8)(2)] (8) were elucidated with the help of DFT and TD-DFT calculations. Complexes [Ni(L1-10)(2)] (1-10) were utilized as catalysts for the synthesis of 1-butene from ethylene using diethyl aluminium chloride as a co-catalyst. A nearly selective formation of 1-butene was observed and productivity up to 17.50 [kg (product/gm catalyst)] h(-1) bar(-1) was found after examining the catalytic activity of complexes 1-10 . A reaction pathway was also proposed for the conversion of ethylene to 1-butene. (C) 2020 Elsevier B.V. All rights reserved.

Zeta potential changing nanoemulsions based on a simple zwitterion

Hypothesis: Simple zwitterions used as auxiliary agents might have the potential to change the zeta potential of oil-in-water (o/w) nanoemulsions on the mucosa. Experiments: The zwitterion phosphorylated tyramine (p-Tyr) was synthesized by phosphorylation of Boc-tyramine (Boc-Tyr) using phosphoryl chloride (POCl3). It was incorporated with 2% (m/v) in a self emulsifying lipophilic phase comprising Captex 35, Cremophor EL, Capmul MCM and glycerol 85 at a ratio of 30:30:30:10 v/v. Phosphate release and resulting change in zeta potential were evaluated by incubating p-Tyr containing nanoemulsion with isolated intestinal alkaline phosphatase (AP). Mucus permeating behavior was evaluated across mucus obtained from porcine small intestinal mucosa. Subsequently, cellular uptake studies were accomplished on Caco-2 cells. Findings: The p-Tyr loaded nanoemulsion exhibited a mean droplet size of 43 1.7 nm and zeta potential of -8.40 mV. Phosphate moieties were rapidly cleaved from p-Tyr loaded nanoemulsions after incubation with isolated AP resulting in a shift in zeta potential from -8.40 mV to +1.2 mV. p-Tyr loaded nanoemulsion revealed a significantly (p <= 0.001) improved mucus permeation compared to the same nanoemulsion having been pre-treated with AP. Cellular uptake of the zeta potential changing oily droplets was 2.4-fold improved. Phosphorylated zwitterions seem to be an alternative to cationic surfactants and considered as promising auxiliary agents for zeta potential changing nanoemulsions. (C) 2020 The Authors.

On the ligand exchange, redox, and disproportionation processes of tetrachloroaurate in the presence of a pyridine derivative

The potential applications of Au-I precursors and pyridine derivatives for shape-directed nanoparticle growth has provided an impetus for the present study of the chemistry of tetrachloroaurate (AuCl4-) in the presence of 4-methoxypyridine (Py-/). Electrochemical experiments show that the addition of Py-/ to AuCl4-leads to the co-existence of both Au-III and Au-I species as evidenced by the observation of two reduction events in the cyclic voltammetry. Kinetic analyses have been used to show that multiple ligand exchange processes occur over the course of several minutes and result in the formation of a Au-III species with two Py-/ and a variable number of chloro and hydroxo ligands in the inner sphere. The kinetics of the initial Py-/ substitution reaction are shown to follow a modified form of the two-term rate law typical of square planar complexes. The observation of a slow, but spontaneous, conversion of Au-III species to Au-I species has been explained by estimating the standard reduction potential for the pyridine/pyridine-N-oxide redox couple and demonstrating that it can drive a galvanic reaction with the AuPy/Cl-2(q)(OH)(2-q)(+)/AuPy2/+ redox couple. The previously reported tendency of this system to form highly anisotropic gold nanoparticles on conductive metal oxide electrodes is explained by a thermodynamic analysis of the disproportionation reaction of AuPy2/+ (C) 2020 Elsevier Ltd.
