The reaction of 5,5,5′,5′-tetramethyl-2,2′-azo-1,1′-pyrroline 1,1′-dioxide with sulphinic acids
Abstract
The title-compound reacts with toluene-p-sulphinic acid in cold ethanol to give 2-(NN-ditoluene-p-sulphonyl-hydrazino)-5,5-dimethyl-1-pyrroline,1-hydroxy-5,5-dimethylpyrrolid-2-one, 5,5-dimethylpyrrolid-2-one, and nitrogen. A scheme is suggested to account for the formation of these products.
