Abstract
Highly dispersed rhenium oxide supported on mesoporous zirconia (Re/m-ZrO2) catalysts were prepared by a simple impregnation method, and excellent catalytic performances were obtained in liquid phase halogenation of aromatic substrates by using hydrogen peroxide and ammonium halide under mild and near neutral conditions. The para-directed selectivity in cases of bromination of aromatic substrates resulted from the stereo effect of the substrates.
