Rh2(esp)2 has been identified as a highly efficient catalyst for O–H insertion of carboxylic acids into acceptor/acceptor diazo compounds. The insertion reaction proceeds in CH2Cl2 within minutes at room temperature in excellent yields and accommodates carboxylic acids having varying functionalities including amino acids, free alcoholic and phenolic O–H, indole N–H, alkenes, alkynes, and substituted
Rh2(esp)2 已被确定为羧酸 O-H 插入受体/受体重氮化合物的高效催化剂。插入反应在室温下几分钟内在 CH2Cl2 中以优异的产率进行,并适应具有不同功能的羧酸,包括氨基酸、游离醇和酚 O-H、吲哚 N-H、烯烃、炔烃和取代的芳烃。此外,该反应耐受各种带有不同官能团的稳定重氮化合物。
