Abstract The reaction of 1-acylisatins with Girard’s reagent T proceeds with elimination of the acyl substituent and the formation of isatin-3-hydrazone with a quaternary nitrogen atom in the side chain. Depending on the structure of the substituent in position 1, 1-(aminomethyl)isatins reacted with the Girard’s reagent T to form hydrazones either with the elimination of the aminomethyl substituent

Depending on the structure of the substituent at the endocyclic nitrogen atom, the reactions of aminomethylisatins with the Girard’s reagent T can proceed both with the elimination of the aminomethyl group and with its retention resulting in the formation of the corresponding positively charged isatin-3-acylhydrazones.
