Quinones 2a,f smoothly underwent the palladium-catalyzedinsertion into the Si−Si bonds of (SiMePhSiMePh-p-C6H4)n (9a), (SiMe2SiMe2CH2CH2)n, and (SiMe2SiMe2O)n to give partially or exhaustively modified polymers with arylenedioxy units incorporated in the backbones. A polysilane, (SiMe2)n, also reacted with 2a to provide a polymer with −SiMe2−O−p-C6H4−O− linkages. Upon UV irradiation, a partially modified
我3 SiSiMe 3与1,2-和1,4-醌(反应p苯醌(2a中),其衍生物,1,2-和1,4-萘醌,9,10-菲醌(2F),9,10- -蒽醌)在钯催化剂的存在下以优异至中等的收率得到相应的双(三甲基甲硅烷氧基)芳族化合物。活性钯催化剂为PdCl 2 L 2(L =叔膦)和Pd(二亚苄基丙酮)2 -2P(OCH 2)3 CEt,其中PdCl 2(PEt 3)2通常是最有效的。1,2-二硅环己烷与2f干净地反应,形成10元环状加合物。Me 3 SiSiMe 2 SiMe 3与2a的反应还通过正式挤出亚甲硅烷基单元得到对-(Me 3 SiO)2 C 6 H 4。用2a处理顺式-(PhMe 2 Si)2 Pt(PMe 2 Ph)2得到p-(PhMe 2 SiO)2 C 6 H参照图4,表明双(甲硅烷基)钯物质参与催化。醌2a,f平稳地经历了钯催化插入(SiMePhSiMePh- p -C 6 H
