Description

<jats:title>Abstract</jats:title> <jats:p>Phenyl isothiocyanate reacted with 2-methylene-1,3-dimethylimidazolidines to give thermally stable, crystalline adducts that possess an inner salt (1,4-dipolar) structure or its tautomeric thioamide structure depending on substituent on the methylene part. Tautomerism between the 1,4-dipolar form and the thioamide form, X-ray diffraction analysis, and 1,4-dipolar cycloaddition with DMAD of these adducts are reported.</jats:p>
