Recently I am researching about ASYMMETRIC REDUCTION; EFFICIENT CATALYST; KETONES; ALDEHYDES; HYDROSILYLATION; COMPLEXES; HYDRIDE; RUTHENIUM; POLY(SILYLETHER)S; HYDROGENATION, Saw an article supported by the National Science FoundationNational Science Foundation (NSF); NSF EPSCoR Award [IIA-1355466]. HPLC of Formula: C8H7NO3. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Vijjamarri, S; O’Denius, TM; Yao, B; Kubatov, A; Du, GD. The CAS is 100-19-6. Through research, I have a further understanding and discovery of 1-(4-Nitrophenyl)ethanone
Hydroboration of carbonyl compounds is an important transformation in organic chemistry, and a growing interest in catalysis has focused on abundant and nontoxic base metals. Herein we describe an efficient salen manganese catalyst for the hydroboration of a broad range of carbonyl compounds with pinacolborane. The catalytic reactions proceeded rapidly (>99% conversion in <5 min) at room temperature with very low catalyst loadings. High turnover frequency (up to 5700 h(-1)) was observed under these conditions. Several synthetically important functional groups were tolerated, and chemoselective hydroboration of aldehydes over ketones was achieved. The H/D kinetic isotopic effect of borane was determined to be 2.3. The Hammett correlation plot of a series of para-substituted acetophenone substrates, p-X-C6H6COCH3 (X = H, Me, OMe, NO2, Cl, Br, and CF3) yielded a positive slope of rho = +0.99. The crossover products were detected in the competition reaction of catecholborane and deuterated pinacolborane with acetophenone. The findings indicated a potential borane-mediated pathway that could account for the observation of the crossover products. HPLC of Formula: C8H7NO3.
