N-Alkyl-N′-tosylhydrazines with Hg(OAc)2 in the presence of alcohols or phenol give high yields of corresponding ethers. Reactions in the presence of acetic acid are also examined.

Oxidation of N-alkyl-N'-tosylhy”razines with bromine yield alkylbromides, vicinal alkyl dibromides and traces of alcohols. The main products of primary hydrazines are monobromides whereas secondary hydrazines preferably produce dibromides. The reaction proceeds with evolution of nitrogen and hydrobromic acid and by the formation of intermediate sulfinic ester which may be isolated. Various substrates
