Attempted preparation of phosphono containing trans-1,2-difluoro-1 phenyldimethylsilyl ethylenes R2P(0)CF=CFSiMePh 3 by deprotonation of HFC = CFSiMe2Ph2 followed by acylation with R2P(0)Cl was unsuccessful. However acylation of the lithium salt of 2 with R2PCl gave R2PCF=CFSiMe2Ph4, which on subsequent oxidation with hydrogen peroxide or tert-butylhydroperoxide afforded a series of compounds trans-R2P(0)CF=CFSiMe2Ph3 in good yields.
