Abstract

Diaryl sulfides have been synthesized in moderate to excellent yield by S-arylation of arenethiols with arylboronic acids using copper slag as a catalyst. Copper slag is a by-product obtained from smelting and refining of copper. Conventional heating method has been compared with the microwave-assisted technique. The proposed microwave-assisted synthesis provides excellent yields of diaryl sulfides in a short time (10 min) and is ligand-free, green, and cost-effective.

微波辅助的铜渣催化的绿色S-芳硫醇与芳基硼酸的芳构化

摘要

碳酸二芳基硫化物已经在温和被合成到由高收率小号使用铜渣作为催化剂的芳基硼酸arenethiols的-arylation。铜渣是通过铜的冶炼和精炼获得的副产品。将传统的加热方法与微波辅助技术进行了比较。拟议的微波辅助合成可在短时间内(10分钟)提供优异的二芳基硫醚收率,并且无配体,绿色且具有成本效益。
