The catalytic properties of alumoxane compounds in the alkylation of 4-methoxyphenol with styrene were studied.Structures and yields of alkylation products depend on the amount of catalyst, the phenol: olefin ratio, and the reaction time.Phenoxyalumoxanes are effective ortho-directing catalysts with respect to the hydroxy group.Under optimum conditions, 2-(α-methylbenzyl)-4-methoxyphenol and 2,5-di-(α-methylbenzyl)-4-methoxyphenol were obtained in 94percent and 84-86percent yields, respectively.
