Treatment of 1-Boc-1-tosyl-hydrazine with 1,1,3,3-tetramethylguanidine (TMG) gave rise to twoproducts, one containing and the other not containing TMG. The latter was identified as 1-Boc-2-tosylhydrazine.This rearrangement provided useful insight into the nature of the first product that had previouslybeen isolated and assigned an incorrect tentative structure. To rationalize the results a plausiblemechanism via a common intermediate, involving TMG as a nucleophilic catalyst is proposed. A simplerprocedure for the preparation of the starting material is also presented.
