Readily available and inexpensive Earth-abundant alkali metal species are used as efficient catalysts for the transesterification of aryl or heteroaryl esters with phenols which is a challenging and underdeveloped transformation. The simple conditions and the use of heterogeneous alkali metal catalyst make this protocol very environmentally friendly and practical. This reaction fills in the missing part in transesterification reaction of phenols and provides an efficient approach to aryl esters, which are widely used in the synthetic and pharmaceutical industry.
容易获得且价格低廉的地球上储量丰富的碱金属物种被用作芳基或杂芳基酯与酚进行酯交换反应的高效催化剂,该反应是一项具有挑战性且尚未充分发展的转化反应。简单的反应条件以及非均相碱金属催化剂的使用使得该方法非常环保且实用。该反应填补了酚酯交换反应中缺失的部分,并为芳基酯提供了一种有效方法,芳基酯在合成和制药工业中广泛应用。
