The reactions of 4,5-dicyanoimidazoles with methyl isocyanate gave 7-cyano-1-imino-2-methyl-2,3-dihydro-1<I>H</I>-imidazo[3,4-<I>c</I>]imidazol-3-ones (<B>2</B>), while the similar reactions with phenyl isocyanate resulted in the formation of the tricyclic imidazoles, 1 1-imino-6,10-diphenyl-2,4,6,8,10-pentaazatricyclo[5.4.1.0<SUP>4,12</SUP>]dodeca-1(12),2,7-triene-5,9-diones (<B>3</B>) and the same type of the tricyclic imidazoles <B>4</B> were obtained by carbamoylation of <B>2</B> with phenyl isocyanate. The reactions of <B>2</B>, <B>3</B>, and <B>4</B> with amines were further investigated.
