Epoxidation Of Cyclohexene

The kinetics, at room temperature, of the oxidation of cyclohexene in the presence of benzaldehyde have been measured, and the nature of the products when this oxidation was performed at 70 and 110 °C has been studied. The results indicate that the attack of benzoyl peroxy radical on the double bond of cyclohexene retards the rate of oxygen absorption and also causes epoxidation of cyclohexene. The epoxidation of cyclohexene by peroxybenzoic acid (produced from aldehyde) seems to proceed simultaneously with the epoxidation by peroxy radicals during the oxidation of cyclohexene in the presence of benzaldehyde.

Terminal Alkenes

Features of the liquid-phase oxidation of alkenes to ketones or aldehydes in the presence of palladium compounds (Wacker oxidation) are discussed in the review. It is shown that the appropriate reaction conditions, namely, the efficient composition of catalyst, oxidant and solvent, make it possible to selectively produce either ketones or aldehydes from terminal alkenes, and ketones from alkenes with the internal double bond.
