undergo direct addition of the nucleophiles to the unsaturated bonds or trigger subsequent rearrangement reactions. This chemistry has witnessed increasing development in recent years. In this report, we have focused on the metal‐catalyzed reactions of a variety of substituted propargyl allenic alcohols and thiophenols using indium(III) and zinc(II) catalysts, which can activate both the alcohol and alkyne
过渡金属活化的炔烃或丙二烯可以接受亲核攻击,并将亲核剂直接加成到不饱和键上,或引发随后的重排反应。近年来,这种化学方法得到了发展。在本报告中,我们重点研究了使用铟(III)和锌(II)催化剂的各种取代的炔丙基烯丙醇和苯硫酚的金属催化反应,它们可以同时激活醇和炔烃。在该反应中,硫基起亲核试剂的作用,并引发随后的重排,生成苯衍生物。通过镍催化的CS键的裂解反应,产物可以进一步转化为各种1,3,5-三取代的芳族化合物。
