摘要：

The highly stereo- and regioselective reaction of 1,3,5-tris(dimethylvinylsilyl)benzene () with -substituted styrenes, -XCHCHCH, where X = H (), Cl (), Br (), vinyl (), catalyzed by RuHCl(CO)(PCy)() appeared to be an efficient basis for new starburst compounds involving silylene−vinylene−arylene sequences. Attempts were made to synthesize the first generation of dendrimer (), based on as a core, via two methods:  direct silylative coupling of 1,3,5-tris[dimethyl(4-vinylstyryl)silyl]benzene () with , which gave a mixture of oligomers containing the SiCHCHSi structure, and successfully via silylation of with vinylsilyl-3,5-bis(isopropoxysilyl)benzene () followed by vinylation with Grignard reagent. Additionally, the double silylation of DVB with followed by vinylation allowed the synthesis of an analogous starburst compound (), which can be a new core for analogous dendritic compounds.
