Treatment of linear alkanesulfinyl chlorides 1 with dry N, N-dimethylmethanamide (DMF), N, N-dimethylethanamide (DMA), or 1-methyl-2-pyrrolidone (NMP) in an inert atmosphere, with or without added solvent, gives S-alkyl alkanesulfonothioates 4 (minor products) and S-1- chloroalkyl alkanesulfonothioates 5. The yield of 4 is decreased in the presence of the radical inhibitor 1, 4-dihydroxybenzene. Evidence has been obtained for the formation ...
