Synthetic Communications | 1976

Substituted 2-Aminobenzoyl Derivatives of Methylhydrazine

Robert W. Leiby; Ned D. Heindel

Abstract Acylation of arylhydrazines gives acyl 2-arylhydrazides1 while acylation of alkylhydrazines yields either 1-alkyl or 2-alkylhydrazides depending on the choice of acylating agent. Earlier examples of the variability of acylation sites in the alkylhydrazines2,3 were systematically reinvestigated by Hinman4 and Moore5 who established that esters, with methylhydrazine, gave acyl 2-methylhydrazides while anhydrides yielded acyl 1-methyl-hydrazides.
