Phosphorus–fluorine chemistry. Part XXII. Alkylthio- and arylthio-substituted fluorophosphoranes
Abstract
Alkylthio- and arylthio-fluorophosphoranes of the types R1SPF4, R1S(R2)PF3, and R1S(R2)2PF2(R1= Me, Et, or Ph; R2= Me or Ph) are prepared in good yields by the cleavage of sulphur–silicon bonds in trimethylsilylsulphides by fluorophosphoranes. The structures of the new compounds are deduced from 19F and 31P n.m.r. data.
