Abstract
4-Thioxothiazolid-2-one (isorhodanine) is distinguished from the initial thiazolidine-2,4-dione, and also from rhodanine and other azolid-4-ones, by the highly active C=S group in position 4. When isorhodanine is heated in methanol with various amino compounds, condensation products-substituted 4-iminothiazolid-2-ones-are obtained.
