For the simultaneous preparation of molecules having both the nucleophilic and electrophilic sites, allyl trimethylsilyl ethers as eletrophilic allylating reagents are studied. Allyl trimethylsilyl ethers react with allyl trimethylsilanes in the pressence of a catalytic amount of ZnCl2 at room temperature to afford the corresponding 1,5-dienes in good yields.
为了同时制备具有亲核和亲电子位点的分子,研究了烯丙基三甲基甲
硅烷基醚作为亲电子的烯丙基化试剂。在室温下,在催化量的ZnCl 2的压力下,烯丙基三甲基甲
硅烷基醚与烯丙基三甲基
硅烷反应,以高收率得到相应的1,5-二烯。
