PREPARATION OF 2,2,6,6-TETRAMETHYL-4-AMINOPIPERIDINE AND ITS SUBSTITUTED COMPOUNDS BY ELECTROREDUCTION OF AZOMETHINES OF 2,2,6,6-TETRAMETHYL-4-OXOPIPERIDINE (TRIACETONAMINE)

Five methods have been developed for electrosynthesis of 2,2,6,6-tetramethyl-4-aminopiperidine in 95 - 98 percent yield via the lead-cathode reduction of 2,2,6,6-tetramethyl-4-oxiimino-piperidine, a mixture of triacetonamine with inorganic salts of hydroxylamine, and a mixture of triacetonamine with nitric acid in a solution of sulphuric acid, via the reduction of azine triacetonamine and of a mixture of triacetonamine with inorganic salts of hydrazine in a neutral solution.The corresponding saturated derivatives of 2,2,6,6-tetramethyl-4-aminopiperidine have been obtained in 60 - 80 percent yield by ele ctroreduction of phenylimine and ethylene diimine.
