In this study, the synthetic potential of the 2,4,6-trimethoxyphenyl (TMOP)-substituted (chloromethyl)silanes (TMOP)Me2SiCH2Cl (1) and (TMOP)2MeSiCH2Cl (2) for the preparation of Si-functionalized (silylmethyl)silanes and α,ω-dichlorocarbosilanes (with skeletons consisting of alternate carbon and silicon atoms) was investigated. Compounds 1 and 2 were used as reagents to introduce the ClMe2SiCH2, MeOMe2SiCH2
在这项研究中,2,4,6-三甲氧基苯基(TMOP)取代的(氯甲基)硅烷(TMOP)Me 2 SiCH 2 Cl(1)和(TMOP)2 MeSiCH 2 Cl(2)的合成潜力研究了硅官能化的(甲硅烷基甲基)硅烷和α,ω-二氯碳硅烷(骨架由交替的碳和硅原子组成)的混合物。化合物1和2用作引入ClMe 2 SiCH 2,MeOMe 2 SiCH 2或Cl 2 MeSiCH 2的试剂通过在硅上的亲核取代形成基团。三步合成方法涉及(i)将1和2转化为(TMOP)Me 2 SiCH 2 MgCl,(TMOP)Me 2 SiCH 2 Li,(TMOP)2 MeSiCH 2 MgCl和(TMOP)2 MeSiCH 2 Li分别(ii)这些亲核试剂与氯代或甲氧基硅烷的反应,以及(iii)随后用HCl / Et 2 O或MeOH / [CF 3 COOH]选择性地裂解TMOP保护基。使用该方法,制备了以下化合物:ClMe
