Cycloaddition Reactions with Azabenzenes, XIII. - Reactions of 1,2.4,5-Tetrazines with FulvenesDepending on the conditions, reaction of 6-dialkylaminofulvenes 1 with 3,6-diphenyl-1,2,4,5-tetrazine (2a) affords 5-dialkylaminomethylene-1,4-diphenyl-5H-cyclopenta[d]pyridazines 10a-d, 3,6-diphenylpyridazine (12), 4-(2-dimethylaminovinyl)-3,6-diphenylpyridazine (13), 9-dimethylaminomethylene- 1,4,5,8-tetraphenyl-4a,4b,8a,9a- tetrahydro-9H-cyclopenta[1,2-d:3,4-d]dipyridazine (14), and 9-dimethylaminomethylene-1,4,5,8-tetraphenyl -9H-cyclopenta-[1,2-d:3,4-d]dipyridazine (15). Compounds 10a and 10b are easily hydrolyzed, yielding 1,4-diphenyl-2-H-cyclopenta[d]pyridazine-5-carbaldehyde (11a) and 1-(1,4-diphenyl-2-H-cyclopenta[d]pyridazine-5-yl)ethanone (11b), respectively. The structures of compounds 10 and 12-15 were determined by spectroscopic methods, chemical reactions or synthesis by an independent route.
