The synthesis of 3,4,7-Triazaacenaphthylene and Pyrido[3,4,5-de]cinnoline derivatives was reported. The title compounds were prepared by four different routes. The reactivity of ylidene derivatives toward different type of organic reagents was described. The mass spectrum and IR spectrum of the products formed by the coupling of ylidene derivatives with diazonium salts were discussed.

Cycloalkylidenemalononitriles couple with various diazonium salts to yield the corresponding cycloalkeno[c]pyridazines, which react with trichloroacetonitrile to give the 1,8-alkanopyrido[3,4-d]pyridazines. The reaction of cycloalkenopyridazines with DMF dimethylacetal gives enamine derivatives, which can be converted to 1,8-alkanopyrido[3,4-d]pyridazines via treating with hydrazine hydrate or aromatic amines. Substituted cycloalkenopyridines react with diazoaminobenzene to afford the corresponding 1,8-alkanopyridopyridazines.
