Abstract

Oxidative conversion of hydrazides of carboxylic acids to acids, esters and amides using Cu salts was studied. Acids were obtained in high yields by using a catalytic amount of Cu (OAc) 2 at room temperature by bubbling oxygen. Hydrazides were converted to esters by the treatment with Cu (OR) Cl or Cu (OR) 2 formed in situ from CuCl2 and sodium alkoxide. Amides were obtained in high yields by the oxidation of hydrazides with CuCl2 in the ...
