CONVENIENT SYNTHESIS OF S-TRIMETHYLSILYL ESTERS OF DITHIO- AND TETRATHIOPHOSPHORIC ACIDS

S-Trimethylsilyl esters of dithio- and tetrathiophosphoric acids were obtained in the reaction of tetraphosphorus decasulfide with alkoxy- and alkylthiotrimethylsilanes, trimethylsilyl enol ethers and bis(trimethylsilyloxy)alkylenes and phenylene. Key words: S-Trimethylsilyl esters of dithio- and tetrathiophosphoric acids; tetraphosphorus decasulfide; alkoxy- and alkylthiotrimethylsilanes; trimethylsilyl enol ethers; bis(trimethylsilyloxy)alkylenes

REACTION OF BIS-- AND BIS--DISULFIDES WITH TRIALKYLSILYLCYANIDES. NEW ROUTE TO DIALKYLPHOSPHORO- AND DIALKYLTHIOPHOSPHORO THIOCYANIDATES AND O,O,O,O-TETRAALKYLPYROPHOSPHOROTRITHIOATES

The reaction of organophosphorus disulfides with trialkylsilylcyanide has been investigated.It provided direct evidence for the intermediacy of thiocyanidate >P(X)SCN, X=O, S in this type of reaction.The disulfides studied involved phosphoryl, phosphonyl and/or phosphinyl disulfides.They have been shown to follow the common mechanism.The studied reaction of thiophosphoryl disulfides with trimethylsilylcyanide represents a new and highly efficient route to tetraalkylpyrophosphorotrithioates.
