A new synthetic protocol for the one-pot, stereoselective synthesis of (E)-poly(arylenevinylene)s via palladium-catalyzed Hiyama cross-coupling of dihaloarenes with cyclic gem-bis(silyl)ethene or isopropoxydimethylvinylsilane is described.
The behavior of alkoxides with allyl(chloromethyl)dimethylsilanes and (chloromethyl)dimethylvinylsilane; the abilities of allyl and vinyl groups to migrate from pentacoordinate silicon
