A novel copper‐catalyzed one‐pot functionalization of homopropargylic alcohols that involves trifluoromethylation, aryl migration, and formation of a carbonyl moiety has been developed. This reaction constitutes the first direct conversion of homopropargylic alcohols into CF3‐containing 3‐butenal or 3‐buten‐1‐one derivatives in a regioselective manner. Mechanistic studies indicate that the 1,4‐aryl
已经开发出一种新型的铜催化的均丙醇单锅功能化,该功能涉及三氟甲基化,芳基迁移和羰基部分的形成。该反应构成了均丙醇以区域选择性方式首次直接转化为含CF 3的3-丁烯醛或3-丁烯-1-酮衍生物。机理研究表明,1,4-芳基迁移是通过自由基途径进行的。
