Abstract

A novel straightforward synthesis of 2-imino-4-thiazolines has been performed by reaction of α-bromoketimines with potassium thiocyanate in acetonitrile. Contrary to other syntheses of these heterocycles, no side reactions were observed. The structural assignment of these relatively rare 2-imino-2, 3-dihydrothiazoles was executed by spectroscopic means, by the synthesis of model compounds by an alternative route and by X-ray crystallographic ...
