ON THE MECHANISM OF ELECTROCHEMICAL EPOXIDATION OF CYCLOHEXENE
Abstract:
The electrochemical epoxidation of cyclohexene has been invest gated on Pt anode in H2O-NaBr-MsCN medium using a rotating disk electrode and a rotating ring-disk electrode.The electrolytic products were identified by means of IR and MS. The results show that cyclohexene was oxidized into epoxycyclohexane by an EC catalytic mechanism: Br-1+H2O→HBrO+H++2e↕HBrO+Cyclohexene
Br-1+O
+H+ The calculated rate constant k1 of the second reaction was (2.1±0.4)×10-2·s-1.
Br-1+O+H+ The calculated rate constant k1 of the second reaction was (2.1±0.4)×10-2·s-1.-
