An efficient method for the synthesis of amides via Pd-catalyzed oxidative carbonylation of C(sp(3))-H bonds with CO and amines is described. The route efficiently provides substituted phenyl amides from alkanes.

polar carboxylic acid and amine substrates. As a consequence, most catalytic amidation protocols are unsuccessful when applied to polar and/or functionalised substrates of the kind commonly used in medicinal chemistry. In this paper we report a practical and useful catalytic direct amidation reaction using tert-butyl acetate as the reaction solvent. The use of an ester solvent offers improvements in terms
