Palladium/NHC-Catalyzed Tandem Benzylic Oxidation/Oxidative Esterification of Benzylic Alcohols with Phenols. — Title tandem benzylic oxidation—oxidative esterification represents a novel efficient access towards aryl benzoates (III) and (V) directly from benzylic alcohols (I), (IV) and phenols (II). Oxygen serves as oxidant. A wide range of functional groups is tolerated, including nitro, cyano, methoxy, ester groups and aromatic halogens. The reaction can also be carried out with allylic alcohol (VI), but formation of the saturated ester (VII) is observed. — (LUO, F.; PAN, C.; CHENG, J.; CHEN*, F.; Tetrahedron 67 (2011) 33, 5878-5882, http://dx.doi.org/10.1016/j.tet.2011.06.060 ; Coll.
