New 1,1-bis(alkoxydimethylsilyl)ethenes have been readily synthesized via ruthenium-hydride complex catalyzed selective silylative coupling cyclization of N,N′-dimethyl-N,N′-bis(dimethylvinylsilyl)ethane-1,2-diamine to yield 1,2,2,4,4,5-hexamethyl-3-methylene-1,5-diaza-2,4-disilacycloheptane, which then undergoes reaction with various alcohols.
新的1,1-双(烷氧基二甲基硅基)乙烯可通过钌氢化物络合物催化选择性硅烷化偶联环化反应,将N,N′-二甲基-N,N′-双(二甲基乙烯基硅基)乙烷-1,2-二胺合成1,2,2,4,4,5-六甲基-3-亚甲基-1,5-二氮杂-2,4-二硅杂环庚烷,然后与各种醇类反应。
