Trapping of benzylic palladium intermediates [generated by aryl to benzyl migration in methylarene derivatives (I) or (VI)] with carboxylates (II) or phenoxide (IV) provides access to the corresponding benzylic esters (III), (VII) or ethers (V) in moderate yields. Under the same reaction conditions, the oxidation of hydroxymethylnaphthalene derivatives (VIII) is smoothly achieved to give the corresponding ketones (IX). The reaction mechanism is discussed in detail.
