Kinetics and mechanism of aromatic electrophilic substitution reactions : VII. Temperature dependence of substrate selectivity of methylbenzene hydroxylation in the system H2O2-H2SO4

The relative rates of the hydroxylation of toluene,ortho-, meta-, andpara-xylenes, mesitylene, and pseudocumene are measured by the kinetic distribution method in the H2O2-H2SO4 (70.0 wt %) system at 15 to 55°C. The activation entropies correlate with the basicities of arenes and the activation enth...
