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

Résumé

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 Co 2 (CO) 8 as catalyst. This results in the cross-linking of PMHS via newly formed Si-C, Si-O-C and Si-O-Si bonds. Our studies also demonstrate the need for intramolecular proximity of Si-H bonds within the polysilane compound to trigger the cross-linking process.
