Abstract The O-allylation of bisphenol A (BPA) has been performed with the most selective catalysts for O-allylation of phenols reported previously. Both the cyclopentadienyl– ruthenium catalysts and the palladium–diphosphine catalysts are capable of selectively performing single and double O-allylation of BPA. An intriguing solvent effect is observed; the choice of the solvent is of key importance for both conversion and selectivity. The use ...
