Abstract

The mixed solvent of ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate and water has efficiently promoted the synthesis of a variety of 5-arylmethylidene-4-oxo-2-thiothiazolidines from the corresponding aromatic aldehydes and rhodanine at room temperature in 80%～93% yields within 10 to 120 min. The present protocol offered several advantages including mild conditions, high yields, short reaction time, and simple work-up procedure. Moreover, the ionic liquid was reusable.

Key words: rhodanine, 5-arylmethylidene-4-oxo-2-thiothiazolidine, aryl aldehyde, ionic liquid
