Cobalt(ii)-catalyzed benzylic oxidations with potassium persulfate in TFA/TFAA?
RSC Advances Pub Date: 2019-07-04 DOI: 10.1039/C9RA03346G
Abstract
A cobalt-catalyzed C(sp3)–H oxygenation reaction to furnish aldehyde was herein reported. This transformation demonstrated high chemo-selectivity, and tolerated various methylarenes bearing electron-withdrawing substituents. This reaction provided rapid access to diverse aldehydes form methylarenes. Notably, TFA/TFAA was used for the first time as a mixed solvent in cobalt-catalyzed oxygenation of benzylic methylenes.
