CuH-catalyzed consecutive hydrosilylation/dehydrocoupling polymerization of difunctional hydroxyketones with dihydrosilanes for syntheses of chiral poly(silyl ether)s

The development of structurally diverse chiral polymers via asymmetric polymerization of prochiral monomers is the frontier in polymeric chemistry. Herein, the easy-to-operate and efficient CuH-catalyzed consecutive asym-metric hydrosilylation/dehydrocoupling polymerization of difunctional hydroxyketone monomers with dihy-drosilanes has been developed, providing the chiral poly(silyl ether)s. This polymerization features atom economy, low catalyst loading, broad substrate scope, mild condition, high stereoselectivity and reactivity. The results of DSC revealed poly(silyl ether)s exhibited good thermal properties.
