Transesterification is one of the important organic reactions employed in numerous industrial as well as laboratory applications for the synthesis of various esters. Herein, we report a rapid, highly efficient, and transition metal-free transesterification reaction in the presence of LiHMDS under solvent-free conditions. The transesterification reaction was carried out with three different benzoate esters and a wide range of primary and secondary alcohols (from C3-C18) in good to excellent yields (45 examples). By considering the commercial role of esters, this method will be promising for the facile synthesis of esters in industry-relevant applications.

LiHMDS：无溶剂条件下的简便，高效和无金属酯交换

酯交换反应是许多工业和实验室应用中用于合成各种酯的重要有机反应之一。在本文中，我们报告了在无溶剂条件下在LiHMDS存在下的快速，高效且无过渡金属的酯交换反应。用三种不同的苯甲酸酯和各种伯和仲醇（来自C3-C18）进行酯交换反应，收率高至优异（45个例子）。考虑到酯的商业作用，该方法有望在工业相关应用中轻松合成酯。
