The photochemistry of some 4-hydroxycyclohexa-2,5-dienones
Abstract
Several hydroxycyclohexadienones, prepared either by oxidation with lead tetra-acetate or peracetic acid of the corresponding phenol or its methyl ether have been photolysed. They yield, initially, unsaturated diketones, which are subsequently transformed into unsaturated lactones. The formation of these products is rationalised.
