Abstract
The combination of palladium acetate and 1,4-bis(diphenylphosphino)butane (dppb) proved once again to form an effective catalytic system for the selective cyclocarbonylation of 2-allylphenols and bis-2-allylphenols. The reactions afforded five-, six- and seven-membered ring lactones and bis-lactones. The seven-membered ring lactones were predominant in most reactions.File in questo prodotto:
