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.
PHOTOREACTIVITE DE DERIVES DE L'ACIDE CARBONIQUE EN MILIEU REDUCTEUR

Photoreduction of carbamates, thiocarbamates and carbonate occurs in a mixture of HMPT-H2O.A better yield of alkane is observed for thiocarbamates.Formates and photoFries products are also isolated from the reaction mixture.Radical intermediates can be trapped by cyclohexene even in HMPA.
