Abstract

The reactivity of trimethylphosphine with ({triple bond, long}SiO)_xZrNp_4-x species (x = 1-3) synthesized on silica dehydroxylated at various temperatures has been studied. Only the bi-grafted ({triple bond, long}SiO)₂ZrNp₂ complex reacts, leading to the formation of a surface alkylidene and evolution of neopentane. In presence of acetone the three neopentyl zirconium species react by the same way with evolution of neopentane and formation of enolate ({triple bond, long}SiO)_xZr[OC(CH₃)({triple bond, long}CH₂)]_4-x species.
