A novel approach for CN bond formation was developed by iron‐catalyzed CC bond cleavage. Anilines and sulfonamides reacted smoothly with 2‐substituted 1,3‐diphenylpropane‐1,3‐diones to afford N‐alkylation products, in which the 1,3‐dicarbonyl group acts as a leaving group in the presence of an iron catalyst. The reversible CC bond cleavage plays a driving force to give the thermodynamically stable
铁催化的CC键裂解产生了一种形成CN键的新方法。苯胺和磺酰胺与2-取代的1,3-二苯基丙烷-1,3-二酮平稳反应,得到N-烷基化产物,其中1,3-二羰基在铁催化剂存在下充当离去基团。可逆的CC键断裂起着驱动力的作用,从而提供了热力学稳定的产物。该方法是对以前形成CN键的方法的补充。
