route to 1,1-bis(silyl)-1-alkenes has been developed. Sequential one-pot silylative coupling exo-cyclization of 1,2-bis(dimethylvinylsiloxy)ethane followed by the reaction with Grignard reagents leads to the desired 1,1-bis(silyl)ethenes, which are then efficiently coupled in the presence of silver nitrate and palladium acetate with aryl or alkenyl idodides to give the corresponding 1,1-bis(silyl)-2-arylethenes
已开发出一种新的选择性合成1,1-双(甲硅烷基)-1-烯烃的方法。顺序一锅silylative耦合外的1,2-双(二甲基乙烯基)乙烷,然后用格氏试剂通向反应-cyclization所需1,1-二(甲硅烷基)ethenes,然后将其有效地在银存在耦合硝酸酯和乙酸钯与芳基或链烯基碘化物一起以高收率得到相应的1,1-双(甲硅烷基)-2-芳烃或1,1,4-三取代的1,3-丁二烯。
