Abstract

Abstract The tetrabutylammonium (TBA) salts of Keggin-type polyoxotungstates of the general formula [XW 11 Fe III (H 2 O) O 39] n−, where X= P, B or Si, were evaluated as catalysts in the oxidation, under mild conditions, of ethylbenzene, cumene, p-cymene and sec-butylbenzene with aqueous H 2 O 2 in CH 3 CN at 80° C. The influence of various factors, such as the substrate/catalyst molar ratio, the amount of oxidant added or the ...
