Synthetic Communications | 1973

Synthesis of Di(7-Cycloheptatrienyl)Ketone

Yasutaka Kayama; Masaji Oda; Yoshio Kitahara

Abstract We here report the synthesis of the title compound which is hitherto unknown and whose chemical and photochemical properties may be of interest.


Journal of The Chemical Society D: Chemical Communications | 1971

Thermal dimerization of (cyanomethylene)cycloheptatriene (8-cyanoheptafulvene); synthesis of a dihydrobenzo[1,2:4,5]dicycloheptene

Masaji Oda; Yasutaka Kayama; Yoshio Kitahara

Thermal dimerization of 8-cyanoheptafulvene (II) gave a dimer, the benzodicycloheptene (III), which may be formed via an 8 + 8-type dimer (VII).
