A silver-catalyzed protocol was found to afford the N-formylation of amines in moderate-to-good yields. Ethylene glycol-derived, oligomeric ethers were found to function as the formylating agent, with 1,4-dioxane affording the best results. This reaction does not require the use of stoichiometric activating reagents, and avoids the use of explosive reagents or toxic gases, such as CO, as the C1 synthon
发现银催化的方案以中等至良好的产率提供胺的N-甲酰化。发现乙二醇衍生的低聚醚起甲酰化剂的作用,其中1,4-二恶烷的效果最佳。该反应不需要使用化学计量的活化剂,并且避免使用爆炸性试剂或有毒气体(例如CO)作为C1合成子。机理研究表明基于单电子转移的途径。这项工作强调了银参与意外反应途径的能力。
