CF3-containing allylic alcohol derivatives were treated with an appropriate Grignard reagent in the presence of catalytic amounts of CuCN and trimethylsilyl chloride (TMSCl) to furnish products via the clean anti-SN2′ mechanism. Experimental results as well as ab initio computational analyses unambiguously demonstrated the important roles of TMSCl as a Lewis basic additive for smooth promotion of reductive
在催化量的CuCN和三甲基甲硅烷基氯(TMSCl)的存在下,用适当的Grignard试剂处理含CF 3的烯丙醇衍生物,以通过干净的抗S N 2'机制提供产品。实验结果以及从头算计算分析清楚地证明了TMSCl作为Lewis碱性添加剂在平滑促进还原消除和抑制“ Cu··F”消除导致重要副产物形成方面的重要作用。
