| Abstract: | The reaction kinetics between O2? and C6H5CH2Br has been investigated in N,N′-dimethylformamide by electroanalytical techniques. A mechanism is proposed in which two molecules of the primary electrode product regenerate, via a following chemical reaction, one molecule of the original electroactive species. Furthermore, evidence for a SN2 reaction mechanism between O2? and C6H5CH2Br has been obtained. Second order rate constants resulted to be 11000 M?1s?1 and 3000 M?1s?1at room temperature and 0°C, respectively. The main products of the reaction were found to be benzylalcohol, benzaldehyde, benzene and biphenyl. |
