Popis: Interaction of nitrosyl chloride with 1-arylimidazolin-2-ones in methanol leads to the formation of 4,5-dimethyoxyimidazolidin-2-ones. Under similar conditions 1,5-diarylimidazolin-2-ones give 1,5-diaryl-4-oximino-5-alkoxyimidazolidin-2-ones. When the reaction is carried out in an aprotic solvent 1,5-diaryl-4-nitrosoimidazolin-2-ones are separated, and when treated with alcohol they give the final reaction products. An increase in temperature and duration of the reaction results in the formation of 1,5-diaryl-5-hydroxyhydantoins.
