Microwave-assisted synthesis of a variety of 1,1-diacetates catalyzed by SbCl₃ from corresponding aldehydes and acetic anhydride was reported. Only 10 mol% of catalyst was sufficient to push the reaction forward and high amounts of the catalyst did not improve the yields to a great extent. The present protocol offered several advantages including low cost of the catalyst, high yields, short reaction time and simple work-up procedure.

SbCl 3催化的醛和乙酸酐的微波辅助无溶剂合成1,1-二乙酸酯

据报道，微波辅助合成了由SbCl ₃催化的相应的醛和乙酸酐合成的1,1-二乙酸酯。仅10mol％的催化剂足以推动反应进行，并且高含量的催化剂没有在很大程度上提高产率。本方案提供了几个优点，包括催化剂的低成本，高产率，短的反应时间和简单的后处理程序。
