Abstract
The catalytic properties of alumoxane compounds in the alkylation of 4-methoxyphenol with styrene were studied. Structures and yields of aikylation products depend on the amount of catalyst, the phenol: olefin ratio, and the reaction time. Phenoxyalumoxanes are effectiveortho-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 94 % and 84–86 % yields, respectively.
