method for the undirected trifluoromethylation of unactivated methylene units was developed. The reaction proceeds in aqueous acetonitrile with Grushin’s reagent, bpyCu(CF3)3, under broad-spectrum white-light irradiation. The trifluoromethylation tolerates a wide range of functional groups including ketones, esters, nitriles, amides, alcohols, and carboxylic acids. The C–H cleavage step is performed
开发了一种用于未活化亚甲基单元的非定向三氟甲基化的简单方法。该反应在乙腈水溶液中与 Grushin 试剂 bpyCu(CF 3 ) 3在广谱白光照射下进行。三氟甲基化可耐受多种官能团,包括酮、酯、腈、酰胺、醇和羧酸。C-H 裂解步骤是通过分子间 H 原子抽象进行的,并且报告了在一系列亚甲基单元上的选择性。机理研究为整体转化提供了一般反应坐标。
