CONTRASTING PHOTOCHEMICAL BRIDGING REGIOSELECTIVITY IN BRIDGEHEAD-SUBSTITUTED 9,10-ETHENO- VS. 9,10-(o-BENZENO)-9,10-DIHYDROANTHRACENES

Article abstract of DOI:10.1016/0040-4039(80)80161-4

The two series of title compounds show contrasting bridging regioselectivity with respect to the bridgehead substituents and are suggested to have different stages of the reactions which determine the ultimate pathway.
