The reactions of mixed O,S-esters of tert-butylthiophosphonous acid and dithiophosphorous acid with 1-chloro-2-organylacetylenes were studied. On the basis of them, a convenient method for the synthesis of thioesters of organylethynylthiophosphinic and dithiophosphonic acids, which are undescribed in the literature, was proposed. A difference was found in the chemical behavior of the methyl ester of S,S-diethyldithiophosphorous acid by comparison with the corresponding complete esters and thioesters of phosphorous acid in reactions with dichloroacetylene.
