摘要

A series of 3-aryl-2-mercaptoacrylic acid derivatives were synthesized by the hydrolysis of 5-(benzylidene) rhodanines in alkaline solution under microwave irradiation. Compared with the classical reaction conditions, this method has the advantage of excellent yields (75 similar to 94%), short reaction time (3 similar to 6 min), environmental benign, low energy consumption and easy work-up.
