The observed rate of oxidation Is first order in both [NCN] and [benzyl ethers). An increase In the dielectric constant of the medium increases the rate. Addition of nicotinamide (NA), the reduction product of NCN, have a negligible effect on the rate of oxidation. A small increase in the rate is observed with increase in [HCIO4] and [NaCI]. Benzaldehyde is identified as the major product of oxidation.
