The rhodium(III)-catalyzed aryl borrowing amination of various diaryl methanols with sulfonamides have been developed. The amination of alcohols via C−C bond activation is less developed and remains a challenge. These aryl borrowing reactions feature mild reaction conditions, good functional group tolerance, and compatibility with a wide range of alcohols, overall comprising an atom- and step-economic
已经开发了铑 (III) 催化的各种二芳基甲醇与磺酰胺的借芳基胺化反应。通过 C-C 键活化对醇进行胺化作用尚不成熟,仍然是一个挑战。这些芳基借用反应具有反应条件温和、官能团耐受性好、与多种醇类相容性好等特点,总体上是一个原子经济和步骤经济的过程。机理研究表明,在芳基借用胺化反应过程中存在红环络合物。
