Abstract
Benzeneseleninic acid (1) and anhydride (2) oxidize hydrazine or 1, 2-disubstituted derivative3 to the corresponding diazenes. Hydrazides afford selenoesters 4, N, N'-diacyl-or- diaroylhydrazines 5, and carboxylic acids. Benzeneselenenic acid (7) is a required intermediate in selenoester formation and may be generated independently by the reaction of triphenylphosphine with 1. Selenoesters are efficiently prepared by the slow addition of ...
