Abstract
Very recently, we reported the regioselective direct ortho borylation of various benzoates or aryl ketones using the complex [Ir(OMe)(cod)] 2 /P[3,5-(CF 3 ) 2 C 6 H 3 ] 3 or AsPh 3 . 7 At the same time, several groups, including Sawamura's, 8 Lassaletta's, 9 and Hartwig's groups, 10 also reported similar borylation of functionalized arenes. The regioselectivity of these reactions is probably driven by the interaction between the coordinating O and N atoms in the directing group ...
