The electrophilic behavior of 4H-imidazolylidene is greatly modified by coordinating groups in benzene derivatives undergoing substitution. Carbenes (Y2C:) react with benzenes (C6H5Z) to give (1) bicyclo[4.l.O]heptadienes (i) which may convert to other bicyclo[4.l.O]heptadienes (;I), cycloheptatrien
Amino-I H-imidazole-4-carboxamide hydrochloride has been converted into a series of new, potentially biologically active N6-substituted 2-azaadenines 5 via 4-diazo-4H-imidazole-5-carbonitrile (1) which was coupled with primary amines to give 5 in 11 -78% yield. Further, some I-substituted 2-azahypox
## Abstract The substituted benzoazoles **__4__** and **__5a,b__** were obtained by the reaction of cyanothioformamides **__1d__** and **__1b__** or **__1c__** with oβsubstituted aromatic amines **__2b__** and **__2c__**, respectively. Fused pyrimidinones **__10, 12__**, and **__14__** were synthes
