A chemoselective and environmentally benign oxidation of benzylic amines into aldehydes mediated by a hypervalent iodine reagent has been developed. This mild oxidative version of the Polonovski process may be selectively carried out in the presence of several functionalities including a free alcohol and provides new synthetic opportunities as a masked aldehyde segment.

Aldehydes are obtained by mild oxidation of benzylic amines with Selectfluor™. The results are compared favorably with the Polonovski-like process using hypervalent iodine.
