Reversible Binding of Ethylene to Silylene–Phosphine Complexes at Room Temperature

Abstract

On and off: The concerted [2+1] cycloaddition reaction of phosphine–silylene complexes with ethylene affords the corresponding pentacoordinate siliranes. The conversion is strongly related to the ethylene pressure, and the reaction is reversible at room temperature. The structure of one silirane was determined by X-ray diffraction analysis.
