Benzyl vinyl ethers have selectively been arylated at either α or β position by fine-tuned Heck-type palladium catalyses. In contrast to previous protocols, no excess of arylating reagent or substrate chelation is necessary. For achieving good yields and high α/β-selectivities various factors determining the catalytic system had to be optimized. The results of DFT computational studies correlate selectivity
苄基乙烯基醚已通过微调的 Heck 型钯催化剂在 α 或 β 位选择性芳基化。与以前的协议相比,不需要过量的芳基化试剂或底物螯合。为了获得良好的收率和高 α/β-选择性,必须优化决定催化体系的各种因素。DFT 计算研究的结果将选择性与 Pd 中心上的电子丰富度相关联。
