Copper(II) Bromide Catalyzed Novel Preparation of Propargylic Ethers and Sulfides by S<sub>N</sub>1-Type Substitution between Propargylic Alcohols and Alcohols or Thiols
A general and efficient copper(II) bromide catalyzed substitution reaction of propargylicalcohols with carbon and heteroatom-centered nucleophiles, such as alcohols and thiols, leading to the construction of C-O and C-S bonds has been developed. High product yields were obtained with excellent regioselectivity.
已经开发了一种通用且高效的溴化铜 (II) 催化炔丙醇与碳和以杂原子为中心的亲核试剂(如醇和硫醇)的取代反应,从而构建 CO 和 CS 键。以优异的区域选择性获得了高产率。
