摘要：

An improved method for the preparation of 2-aryl-, 2-hetaryl- and 2-styrylbenzothiazoles by interaction of aryl aldehydes, heterocyclic aldehydes and cinnamaldehydes with 2-aminothiophenol in dimethyl sulphoxide with simultaneous removal of the volatile reaction products is described. The method offers a simple experimental procedure, higher yields and shorter reaction times. © 1990.
