4,5-Diphenyl-4-oxazolin-2-one and -2-thione undegro recyclization to 1-substituted 4,5-diphenyl-4-imidazolin-2-ones and -2-thiones, respectively, under the influence of primary amines.The action of hydrazine hydrate on the oxazolone leads to 5,6-diphenyl-1,2,3,4,-tetrahydro-1,2,4-triazin-3-one.The corresponding ureas were isolated from the reaction mixtures in a number of cases.
