Using a Pd-NHC catalyst for cross-coupling of phenyl esters and alkyl boranes, alkyl ketones can be prepared in good yields via a Suzuki-Miyaura reaction proceeding by activation of the C(acyl)-O bond, whereas a Pd-dcype catalyst provides alkylated arenes by a modified pathway with extrusion of CO.
