Abstract
Abstract Here, we describe that polymethylhydrosiloxane (PMHS) is a sustainable terminal reductant in the titanocene catalyzed hydrosilylation of epoxides. The products formally constitute the anti ‐Markovnikov products of H 2 O‐addition to alkenes. PMHS is not only a more sustainable and cheaper reductant than other silanes such as PhSiH 3 and Ph(Me)SiH 2 . It also results in a higher diastereoselectivity of epoxide reduction.
