Co₂(CO)₈ and unsaturated epoxides as unexpected partners in generating functionalized siloxane oils and cross-linked materials

Abstract

Herein, we describe the unexpected ring opening of the epoxide group of allyl glycidyl ether and 4-vinylcyclohexene oxide in polymethylhydrosiloxane (PMHS) hydrosilylation reaction using 0.1 mol% of Co2(CO)8 as catalyst....

MnBr(CO)5: a commercially available highly active catalyst for olefin hydrosilylation under ambient air and green conditions

“…25 This complex could also perform the crosslinking of industrially relevant allyl glycidyl ether or 4-vinylcyclohexene oxide as unconventional tethers with PMHS. 26 This catalytic system thus offered a unique method for the cross-linking of PMHS with traditional dienes and unconventional organic tethers, such as (un)saturated esters. These results showed that catalytic systems based on commercially available and structurally simple non-noble metal complexes (without specific ligands) could be of interest in the field of hydrosilylation.…”
