Synthesis and reactions of [1-(trialkylsilyl)alkylidene]triphenylphosphoranes

Alkylidenetriphenylphosphoranes 1 react with trialkyl halosilanes 2 to afford silylated alkylidenephosphoranes 5, which can be converted to acylated alkylidenephosphoranes 8 and 10 by trimethylsilyl carboxylates 6 or carboxylic anhydrides 10. Bis(acylalkylidenephosphoranes) 13-15 are available from 5 and bis(trimethylsilyl) dicarboxylates 12 or cyclic or polymeric anhydrides 16, 17.
