Og. Sinyashin et al., REACTIONS OF MIXED O,S-ESTERS OF ACIDS OF TRIVALENT PHOSPHORUS WITH SUBSTITUTED 1-CHLOROACETYLENES, Bulletin of the Russian Academy of Sciences, Division of Chemical Sciences, 41(7), 1992, pp. 1264-1265
The reactions of mixed O,S-esters of tert-butylthiophosphonous acid an
d dithiophosphorous acid with 1-chloro-2-organylacetylenes were studie
d. On the basis of them, a convenient method for the synthesis of thio
esters of organylethynylthiophosphinic and dithiophosphonic acids, whi
ch are undescribed in the literature, was proposed. A difference was f
ound in the chemical behavior of the methyl ester of S,S-diethyldithio
phosphorous acid by comparison with the corresponding complete esters
and thioesters of phosphorous acid in reactions with dichloroacetylene
.
