Urea in formic acid is a general and practical reagent for the reductive aminoformylation of benzophenones and fluoren-9-one in the synthesis of N-diarylmethylformamides, which exhibit antispasmodic activity.With benzophenone in formic acid 1,3-dimethylurea gives a high yield of N-methyl-N-benzhydrylformamide.Urea reacts selectively with benzil and benzoin, forming both the bicyclic bisurea and monocyclic nitrogen-containing heterocycles, depending on the temperature.It was proposed for the first time to use arylmethylenebisureas as reagents in reaction with benzil for the production of 1,5-diphenyl-2,4,6,8-tetraazabicyclooctane-3,7-dione or 2,4,5-triphenylimidazole.
