1-Tri(phenyl, methyl)silyl-1-alkenes of the general formula RCHCHSiMe3−n Phn (where n = 1-3, R = CmH2m+1, m = 5, 6, 8, 10, and 12; Ph) have been prepared by a novel method, viz. by a very effective cross-metathesis of vinyltri(phenyl, methyl)silanes with 1-alkenes and styrene catalyzed by ruthenium and rhodium complexes. A tenfold excess of 1-alkene in the reaction mixture gave stereospecific 1-tri(phenyl
通式RCH = CHSiMe 3- n Ph n的1-Tri(苯基,甲基)甲硅烷基-1-烯烃(n = 1-3,R = C m H 2 m +1,m = 5,6,8 ,10和12; Ph)已通过一种新颖的方法制备。通过钌和铑配合物催化的乙烯基三(苯基,甲基)硅烷与1-烯烃和苯乙烯的非常有效的交叉复分解反应。反应混合物中过量十倍的1-烯烃以高达90%的高收率(进而转化为乙烯基硅烷)得到了立体定向的1-三(苯基,甲基)甲硅烷基-1-烯烃(主要为E-异构体)。产物通过光谱鉴定(IR,拉曼,1H,13 C NMR和GC-MS)方法。
