Abstract

o-Iodoxybenzoic acid (IBX)/iodine in dimethyl sulfoxide at 65 °C oxidatively and efficiently converted various amines into the corresponding nitriles in good to excellent yields. Under the reaction conditions, amines were selectively oxidized to the nitrile in the presence of a primary hydroxy group within the same molecule.

All nitriles gave satisfactory spectroscopic data and were identified by comparison with those previously reported in literature.
