Photoreduction and reduction of carbonic acid derivatives in HMPT have been compared.The highest yield of alkane was obtained from N,N-dimethylthiocarbamates either by the photochemical method or by reduction with a dissolved metal.Competitive reactions have been characterized: - during the photoreduction not only the alkane but products of a photo-Fries rearrangement and products of a homolytic cleavage were detected; - basic reactions can compete with the reduction of carbonic acid derivatives by sodium in HMPT.
