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.
