Abstract
1528179 spiroimidazolines AGFAGEVAERT AG 18 Dec 1975 [20 Dec 1974 28 June 1975] 51808/75 Heading C2C [Also in Divisions G2-G3] Spiroimidazolidine compounds of the formula in which R and R<SP>1</SP> which may be the same or different, represent hydrogen, alkyl, aryl, aralkyl, cycloalkyl or halogen, or R and R<SP>1</SP> together represent the carbon atoms required to complete a condensed cyclohexene, cyclohexadiene or benzene ring, X represents oxygen or -NH- and Y represents oxygen, sulphur or -NH- are prepared by reacting cyanamide with oxalyl chloride to give 2,2-dichloroimidazolidine-dione-(4,5) which is then reacted with the appropriately ortho-disubstituted phenyl compound. In an example the compound used is pyrocatechol, the product being spiro- [1,3 - benzodioxol - 2,21 - imidazolidine] - 4<SP>1</SP>,5<SP>1</SP>- dione. In place of pyrocatechol there can be used 4 - chloropyrocatechol, 4,5 - dichloropyrocatechol, 3,4 - dihydroxy - tert.butylbenzene, 3,4 - dihydroxy - cyclohexylbenzene, 3,4 - dihydroxy - tert.octyl - benzene, oaminophenol, o - aminothiophenol and ophenylenediamine.
