Patent ID: 8772523

Claim:
A process for preparing a multifunctional chain shuttling agent, the process comprising steps of: contacting a hydroxy-, thiol- (i.e., —SH), hydrocarbylamino-, amino- (i.e., —NH 2 ), hydrocarbylphosphino-, or phosphino- (i.e., —PH 2 ) and vinyl-containing polyvalent group to an alkylperhydrocarbylmetal to respectively prepare an organometallic intermediate that is a hydrocarbylmetal vinyl-alkoxide, hydrocarbylmetal vinyl-sulfide, hydrocarbylmetal vinyl-(hydrocarbyl)amine, hydrocarbylmetal vinyl-amine, hydrocarbylmetal vinyl-(hydrocarbyl)phosphine, or hydrocarbylmetal vinyl- phosphine; and contacting the organometallic intermediate to a hydrocarbylmetal monohydride, thereby preparing the multifunctional chain shuttling agent, each metal independently being a cation of tin or a metal of any one of Groups 2, 12, and 13 of the Periodic Table of the Elements.
