Oxidation of Methylidene Groups to Carbonyl Groups

Oxidation of Methylidene Groups to Carbonyl Groups: Mechanism

This oxidation is a catalytic reaction involving organometallic complexes. Ethylene is oxidized by intermediary oxypalladation (addition of palladium and hydroxy group to a double bond) followed by fragmentation of the α-hydroxyethyl-σ-complex to the carbonyl compound.

The individual steps are shown below for the oxidation of ethylene.
