Abstract
Acylhydrazines1 and their metal complexes2 have been found to possess a variety of biological activities. They are also frequently used as starting materials for the synthesis of heterocyclic compounds3 and multisubstitued hydrazines.4 Generally, acylhydrazines are prepared by the acylation of hydrazines with acylchlorides,5 anhydrides or esters.6 A carboxylic acid was recently used for a direct conversion of hydrazines into acylhydrazides with lipase as the catalyst,7 ...
