Abstract
A new optically active (>99% ee) organosilicon compound, 1-(1-naphthyl)-1-phenyl-1-vinyl-3,3-dimethyl-3-hydro-1,3-disiloxane was prepared. This bifunctional disiloxane was used as the monomer to synthesize optically active and isotactic poly[{(1S)-1-(1-naphthyl)-1-phenyl-3,3-dimethyldisiloxane-1,3-diyl}ethylene] via hydrosilylation in the presence of the platinum−1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex. This polymer with the optical activity induced by main chain asymmetric silicon units proved to be optically pure (>99% ee) and highly stereoregular (isotacticity > 99%).
