Palladium-catalyzed oxygenation of unactivated sp3 C-H bonds

J Am Chem Soc. 2004 Aug 11;126(31):9542-3. doi: 10.1021/ja046831c.

Abstract

This communication describes a new palladium-catalyzed method for the oxygenation of unactivated sp3 C-H bonds. A wide variety of alkane substrates containing readily available oxime and/or pyridine directing groups are oxidized with extremely high levels of chemo-, regio-, and in some cases diastereoselectivity. The substrate scope of these reactions is discussed, and the high selectivities are rationalized on the basis of the requirements of putative palladium alkyl intermediates.
