Poly(methylhydrosiloxane) as a reductant in the catalytic base-free Wittig reaction

Abstract

PMHS proved to be a suitable terminal reductant for P(<sc>iii</sc>)/P(<sc>v</sc>) redox cycling with a methyl-substituted phosphetane as catalyst and BuOAc as solvent. The formation of water by silanol condensation was identified as main pathway of siloxane formation.
