Abstract

Abstract Five methods have been developed for electrosynthesis of 2, 2, 6, 6-tetramethyl-4- aminopiperidine in 95-98% 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 ...
