Özet

Unsaturated fulvene endoperoxides (2a-e) were trapped with dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate (4). The formed saturated fulvene endoperoxides containig 1,2-dihydropyridazine ring (6a-e) were characterised by spectroscopic methods. Treatment of (6a-e) with cobalt(II) tetraphenylporphyrin (CoTPP) provided alkylidene- and arylidenemalonaldehydes (9a-e).
