PHOTOCHEMICAL REACTIONS OF N-THIOAROYLUREAS AND N-THIOAROYLTHIOUREAS
Irradiation of N-thioaroylureas and N-thioaroylthioureas gave imidazolidinones and imidazolidinethiones, respectively both via intramolecular hydrogen abstraction by the thioaroyl groups; the photoproducts were easily converted to the imidazolones and imi

PHOTOCHEMICAL REACTIONS OF N',N'-DIALKYL-N-aroylureas
N',N'-Dibenzyl and N',N'-diisopropyl-N-aroylureas undergo cyclization on irradiation to give the corresponding imidazolidin-2-ones via intramolecular hydrogen abstraction by the aroyl carbonyl group.
