A novel decarboxylative difluoromethylation reaction of PhSO2CF2COOK with aldehydes under metal- and ligand-free conditions has been developed. The reaction is very mild and tolerates a wide range of aldehydes (both enolizable and non-enolizable aldehydes), providing a facile and efficient method for the synthesis of structurally diverse difluoromethylated carbinols in moderate to excellent yields
在无金属和无配体条件下,开发了PhSO 2 CF 2 COOK与醛类的新型脱羧二氟甲基化反应。该反应非常温和,并且可以耐受多种醛类(可烯醇化和不可烯醇化的醛),为合成结构多样的二氟甲基化甲醇提供了简便而有效的方法,产率中等至优异。
