iron-catalyzed esterification of allylic sp3 C–H bonds with carboxylic acids using ionic iron(III) complexes (1–4) as a catalyst and DTBP (DTBP = di-tert-butyl peroxide) as an oxidant is achieved. A variety of allylic esters were synthesized in good to excellent yields using the ionic iron(III) complex 2 as a catalyst in a 5 mol% loading. This reaction is characterized by its high efficiency, broad substrate

We described that copper 5,10,15,20-tetrakis (ethoxycarbonyl)porphyrin (TECP) catalyzed oxidative cross dehydrogenative coupling of allyl sp3 CH bond with acid for the synthesis of allyl esters in a homogeneous system. This reaction proceeded with broad substrate scope and good functional group tolerance. In the gram-level test, the turnover number (TON) reached to 8100 at 0.01 mol% catalyst loading

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.
