Abstract
The kinetics of oxidative hydrolysis of aromatic anils by potassium br omate have been studied in aq. acetic acid (50%, v/v) containing HClO4 (0.20 mol dm-1) at 27 +/- 0.2-degrees-C in the presence of Hg(OAc)2 ( 0.01 mol dm-3). The reaction exhibits total second order kinetics-firs t order in each reactant. The presence of electron withdrawing group l ike p-NO2 in the aniline portion increases the rate markedly. A mechan ism involving nitrene intermediate, is proposed to account for the sto ichiometry and products, namely, benzaldehyde and azobenzene.
