The present article describes novel oxidative protocols for direct esterification of alcohols. The protocols involve successful demonstrations of both “cross” and “self” esterification of a wide variety of alcohols. The cross‐esterification proceeds under a simple transition‐metal‐free condition, containing catalytic amounts of TEMPO (2,2,6,6‐tetramethyl‐1‐piperidinyloxy)/TBAB (tetra‐n‐butylammonium
本文介绍了醇直接酯化的新型氧化方案。该方案包括成功地演示了多种醇的“交叉”和“自身”酯化。交叉酯化反应在简单的无过渡金属条件下进行,其中包含催化量的TEMPO(2,2,6,6-四甲基-1-哌啶基氧基)/ TBAB(四正丁基溴化铵)与恶唑酮(过氧单硫酸钾)作为氧化剂,而自酯化是通过在相同的氧化环境下简单诱导Fe(OAc)2 / dipic(dipic = 2,6-吡啶二羧酸)作为活性催化剂来实现的。
