efficient and solvent-free method for the one-pot synthesis of allylic esters via dehydrogenation of unactivated alkanes and subsequent oxidative cross coupling with different substituted carboxylic acids. A simple, well defined and air stable Cu(II)-complex, [Cu(MeTAA)], featuring a tetraaza-macrocyclic ligand (tetramethyltetraaza[14]annulene (MeTAA)) is used as the catalyst. A wide variety of substituted

A metal-free C H oxidation for the construction of allylic esters has been developed. The use of a commercially available and inexpensive catalyst and oxidant, and readily available starting materials, coupled with the operational simplicity of the reaction, renders the methodology a useful alternative to other approaches typically employed in the synthesis of allylic esters.
