A palladium/NHC-catalyzed tandembenzylicoxidation/oxidative esterification of benzylicalcohols with phenols to access aryl benzoate derivatives is described. The procedure tolerates a series of functional groups, such as methoxy, nitro, cyano, chloro, fluoro and bromo groups. Thus, it represents a practically alternative method to access aryl benzoate derivatives.

An efficient methodology to access benzoate derivatives via tandembenzylicoxidation/oxidative esterification of benzylicalcohols with phenols catalyzed by ruthenium/NHC was developed. This operationally simple one-pot process uses O2 as the clean oxidant, producing esters in good to excellent yields.
