Palladium/NHC-Catalyzed Oxidative Esterification of Aldehydes with Phenols. — A broad spectrum of aromatic aldehydes and phenols can be used in the presence of air as a clean oxidant. With exception of (XIg), yields are moderate to good and various functional groups are tolerated. In the series of aliphatic aldehydes tested, only the cy-clohexyl derivative is reactive [cf. (Va)]. — (ZHANG, M.; ZHANG, S.; ZHANG, G.; CHEN*, F.; CHENG, J.; Tetrahedron Lett. 52 (2011) 19, 2480-2483, http://dx.doi.org/10.1016/j.tetlet.2011.03.017 ; Coll. Chem. Mater.
