Sulfonyl hydrazides and sulfonyl semicarbazides are readily prepared by the reacting of hydrazine derivatives with sulfonyl chlorides in the presence of basic alumina under solvent-free conditions. Reaction of a sulfonyl chloride with t-butylcarbazate, followed by hydrolysis provides the corresponding sulfonyl hydrazides in higher yield and shorter time than previously reported.
