Synthesis and Characterization of Dibenzo[a,f]pentalene: Harmonization of the Antiaromatic and Singlet Biradical Character

Mesityl derivatives of the unknown dibenzopentalene isomer dibenzo[a,f]pentalene were synthesized. The molecular geometry and physical properties of dibenzo[a,f]pentalene were investigated. Dibenzo[a,f]pentalene combines a large antiaromatic and appreciable singlet open-shell character, properties not shared by well-known isomer dibenzo[a,e]pentalene.

Trapping of unsaturated fulvene endoperoxides with dimethyl 1,2,4,5- tetrazine-3,6-dicarboxylate: A new synthesis of alkylidene- and arylidenemalonaldehydes

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).
