已经报道了从N-烷氧基酰胺合成酚酯的电化学开-关方法。这种一锅法的协议开始于使用n- Bu 4 NI(TBAI)作为电催化剂对酰胺进行快速和选择性的电二聚。在不存在电流的情况下,该反应会进一步通过酰胺催化的二聚体的Zn催化C-N键活化而进行,然后将其与苯酚偶联形成酯。本方法学不含配体,在温和的反应条件下进行。这种转变结合了多种酚和酰胺底物,导致形成功能化的酯,从而突出了其多功能性。
The esterification of carboxylicacids is an important reaction for preparing esters which find wide applications in various research fields. In this manuscript, we report an acid/iodide cooperative catalytic method which enables highly efficientesterification of carboxylicacids with a wide range of equivalent O–H nucleophiles including both alcohols and weak nucleophilic phenols. Under the reaction
