Palladium acetate [Pd(OAc)2] and 1,4-bis(diphenylphosphino)butane (dppb) are effective catalysts in cyclocarbonylation of allylic cardanol and cardol derivs., producing 7-membered ring lactones regioselectively in good yields. The 6-tert-butyl-2-(1-methylallyl)-3-n-pentadecylphenol exhibits excellent antioxidant activity, for potential use as stabilizer for polymers processed at high temps.
