alkyl 2-benzylacrylates and 2-benzylacrylonitriles were synthesized by means of atom-economic cross-couplings of Baylis–Hillman bromides or acetates with BiAr3 under palladium-catalyzed conditions. These reactions, involving threefold aryl couplings using BiAr3 reagents with bromides and acetates, are fast and are completed in 1–2 h with high product yields.
在钯催化条件下,通过 Baylis-Hillman 溴化物或乙酸盐与 BiAr3 的原子经济交叉偶联合成了功能化的 2-苄基丙烯酸烷基酯和 2-苄基丙烯腈。这些反应涉及使用 BiAr3 试剂与溴化物和乙酸盐进行三重芳基偶联,反应速度快,在 1-2 小时内完成,产品收率高。
