REACTIONS OF MIXED O,S-ESTERS OF ACIDS OF TRIVALENT PHOSPHORUS WITH SUBSTITUTED 1-CHLOROACETYLENES

Article abstract of DOI:10.1007/BF00864193

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 behaviour 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.Keywords:thioesters of P(III) acids, 1-chloroacetylenes, organylethynylthiophosphinates, organylethynyldithiophosphonates, Arbuzov reaction.
