This work may give an understanding of why epoxide and aldehyde are easily generated in olefin oxidation by molecular oxygen when vanadium phenoxyimine complex was employed as a catalyst. This work would also explain why oxetane and dioxetane were harder to produce, although a radical tautomerism may allow the formation of such products.

Oxidation Of Carbon Monoxide

The kinetics of the copper (II)-catalyzed oxidation of carbon monoxide by molecular oxygen, i.e. [Formula: see text] have been investigated in aqueous solutions at 120 °C. The rate law was found to be of the form −d[O2]/dt = kexpt[O2][CO][Cu(II)]/[H+], where kexpt = 7.88 × 10−6 M−1 s−1 in 0.25 M acetate solutions. The apparent activation energy is 29 600 cal/mole. The rate-determining step of the reaction appears to be the oxidation by molecular oxygen of a carbon monoxide insertion complex [Formula: see text] formed in the pre-equilibrium step.
