## Abstract The reaction of copper with benzyl bromides in hexamethylphosphoramide has been studied. The kinetic and thermodynamic parameters of the reaction have been obtained. Hammett plots of log (__k__/__k__^o^) vs the substituent constant ฯ gave good correlations (ฯ = 0.15, __S__~ฯ~ = 0.02, __
The kinetics of oxidation of N,N-dimethylformamide by chromium(VI) has been studied spectrophotometrically in aqueous perchloric acid media at 20ะC. The rate showed a first-order dependence on both [Cr(VI)] and [DMF], and increased markedly with increasing [H ฯฉ ]. The order with respect to [HClO 4 ]
## Abstract The reaction of copper with benzyl bromides in dipolar aprotic solvents has been studied. There are no linear or other simple relations between ฮต, 1/ฮต, __Y__, __P__, __n__, and the rate of reaction. The activity of the solvent is determined by donor number (DN) in reaction under conside
