1,3-Diketones, as novel acylation agents, reacted with aromatic amines promoted by commercially available H2O2 (30% aq.) as the sole oxidant at room temperature under metal-free conditions in water, leading to a novel and rapid amide bond formation strategy. The reported method is high-yielding, simple and mild, and is the first example of the use of 1,3-diketones as acylation agents via CâC bond cleavage.
1,3-二酮作为新型酰化试剂,在室温下以水为反应介质,在无金属的条件下,依靠商业可得的30%水合过氧化氢(H2O2)作为唯一氧化剂,与芳香胺反应,形成了一种新颖且快速的酰胺键形成策略。该方法具有高产率、简单温和,是首次通过C–C键断裂使用1,3-二酮作为酰化试剂的例子。
