A simple and efficient catalytic system including 3-methyl-4-oxa-5-azahomoadamantane and FeCl3 for aerobicoxidative synthesis of benzimidazoles from primaryamines and o -phenylenediamine is presented. This process uses O2 as economic and green oxidant and water as green solvent, tolerates a wide range of substrates, and can afford the target products in moderate to excellent yields.
Oxoammonium salt/NaClO2: an expedient, catalytic system for one-pot oxidation of primary alcohols to carboxylic acids with broad substrate applicability
A facile, green, one-pot oxidation of primary alcohols to carboxylic acids with broad substrate applicability has been developed by employing an expedient catalytic system consisting of 1-Me-AZADO+X−/NaClO2.
Development of a stable nitroxyl radical class of catalysts, 2-azaadamantane N-oxyl (AZADO) and 1-Me-AZADO, for highly efficient oxidation of alcohols is described. AZADO and 1-Me-AZADO exhibit superior catalytic proficiency to TEMPO, converting various sterically hindered alcohols to the corresponding carbonyl compounds in excellent yields.
