Lu, Bing published the artcileIron-catalyzed esterification of allylic sp3 C-H bonds with carboxylic acids: Facile access to allylic esters, HPLC of Formula: 258278-25-0, the publication is Tetrahedron Letters (2017), 58(25), 2490-2494, database is CAplus.
The first general and efficient iron-catalyzed esterification of allylic sp3 C-H bonds with carboxylic acids using ionic iron(III) complexes as a catalyst and DTBP (DTBP = di-tert-Bu peroxide) as an oxidant is achieved. A variety of allylic esters were synthesized in good to excellent yields using an ionic iron(III) complex as catalyst in a 5 mol% loading. This reaction is characterized by its high efficiency, broad substrate scope with excellent steric hindrance tolerance and good functional group compatibility.
