Abstract

Imidazolidones of general formula <FORM:1065295/C2/1> wherein R represents a hydrogen atom or a lower alkyl group, optionally substituted by a halogen atom, and R1 is an aliphatic, aromatic (including arylsulphonyl), araliphatic or cycloaliphatic group, all optionally substituted, e.g. by a halogen atom or a lower alkoxy or alkyl or nitro group, are prepared by reacting an oxazolidone of the general formula <FORM:1065295/C2/2> with an organic isocyanate compound having the formula R1-N = C = O at an elevated temperature and preferably in the presence of a catalyst, e.g. a tertiary amino base or lithium chloride.
