Symmetrical 1,1-bis(silyl)ethenes have been easily prepared via ruthenium complex-catalyzed silylative coupling cyclization of 1,2-bis(dimethylvinylsiloxy)ethane to give 2,2,4,4-tetramethyl-3-methylene-1,5-dioxa-2,4-disilacycloheptane with excellent selectivity and good yield, followed by its reaction with Grignard reagents. The cyclic product can also be effectively transformed into cyclic carbosiloxane
对称的1,1-双(甲硅烷基)乙烯很容易通过钌络合物催化的1,2-双(二甲基乙烯基甲硅烷氧基)乙烷的硅烷化偶联环化反应制得2,2,4,4-四甲基-3-亚甲基-1, 5-二恶英-2,4-二硅环庚烷具有优异的选择性和良好的收率,随后与格氏试剂反应。环状产物也可以有效地转化成环状碳硅氧烷,2,2,4,4,6,6,8,8-八甲基-3,7-二亚甲基-1,5-二氧杂-2,4,6,8-四硅环辛烷。
