o-Iodoxybenzoic acid- and tetraethylammonium bromide-mediated oxidative transformation of primary carboxamides to one-carbon dehomologated nitriles.

A clean and efficient method for the oxidative transformations of primary carboxamides to one-carbon dehomologated nitriles using the combination of o-iodoxybenzoic acid and tetraethylammonium bromide has been developed. This method exhibits a broad scope and is expected to be of great utility in organic synthesis.
