Abstract

The RuH2 (CO)(PPh3) 3-catalyzed C–H functionalization of aromatic esters with 5, 5- dimethyl-2-aryl-[1, 3, 2] dioxaborinanes (arylboronates) gave the ortho arylation products. This coupling reaction can be performed with various combinations of isopropyl benzoate derivatives and arylboronates. Introduction of CF3 group in the aromatic ring increased the reactivity of the esters. Pinacolone effectively served as an acceptor of a hydride ...
