ChemInform Abstract: Valence Isomerization of Norbornadienes Containing a Carbonyl Group.

Abstract

1993 valence isomerism processes valence isomerism processes O 0150 -086Valence Isomerization of Norbornadienes Containing a Carbonyl Group.-Norbornadienes such as (III) and (VII) are found to undergo isomerization to tetracyclic compounds of type (IV) and (VIII) on irradiation. Treatment of the tetracyclic compounds with TFA or MoO3 leads to the starting norbornadienes. -(CHERNOIVANOV, V. A.; DUBONOSOV, A. D.; BREN', V. A.; MINKIN, V. I.; GALICHEV, S. V.; SUSLOV, A. N.; Zh.
