Features of Reactions of Some 1-Arylaminomethylisatins with Girard’s Reagent T

详细

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.
