Photochemical studies on unsaturated ketones

Photocycloaddition reactions of trans-[beta]-nitrostyrene

“…The susceptibility of a number of olefinic substrates to at tack by excited 2-cyclohexenone has been measured by competi tion experiments which establish the series: 1,1-dimethoxy- (22)(23)(24)(25)(26)(27)(28), but they will not be discussed since they are not directly related to this study.…”
