Kornblum oxidation

The Kornblum oxidation is a chemical reaction of a primary halide with dimethyl sulfoxide (DMSO) to form an aldehyde. Like all DMSO-based oxidations, the Kornblum oxidation creates an alkoxysulphonium ion, which, in the presence of a base, such as triethylamine (Et3N), will eliminate to form the desired aldehyde.
