Reaction of triarylbismuth difluorides 1 with allyltrimethylsilane 2 in CH2Cl2 in the presence of BF3·OEt2 at low temperature generates allyltriarylbismuthonium compound 3 as a pale yellow solution, in which aromatic hydrocarbons and ethers, triphenylphosphine, dimethyl sulfide, p-toluenesulfinate, and thiophenol are all readily allylated to afford the corresponding allyl derivatives in moderate to
BF 3 ·OEt 2的存在下,三氟化三芳基铋1与烯丙基三甲基硅烷2在CH 2 Cl 2中在低温下反应生成烯丙基三芳基双mut化合物3,为浅黄色溶液,其中芳烃和醚,三苯膦,二甲基硫醚,对甲苯磺酸盐和苯硫酚都容易被烯丙基化,以中等至良好的产率得到相应的烯丙基衍生物。
