In the presence of acids or bases or on heating 2,6-di-tert-butyl-4-(4,5-dimethoxy-2-phenacylbenzylidene)-2,5-cyclohexadien-1-ones are converted into isochromenes; treatment with hydroxylamine yields isoquinoline derivatives possessing high antioxidant activity.Reactions of these methylenebenzoquinones with elemental sulfur and selenium result in formation of 1,2-dihydro-2-thia(selena)naphthalene 2-oxides.
