The direct, nucleophilic imidation of acetanilide derivatives has been performed under mild, iodine(III)‐mediated or ‐catalyzed conditions, employing lithium triflimide as the nitrogen source. The reaction exhibits exclusive regioselectivity for the para position and shows a good tolerance for varied functional groups at both the ortho or meta positions. Preliminary mechanistic data suggest that the
对乙酰苯胺衍生物的直接亲核酰亚胺化反应是在温和的,碘(III)介导或催化的条件下进行的,使用三氟化锂作为氮源。该反应对对位具有排他性的区域选择性,对邻位或间位的各种官能团均表现出良好的耐受性。初步的力学数据表明,LiNTf 2试剂在反应性中起关键作用。
