Hoque, Emdadul Md published the artcileNoncovalent interactions in Ir-catalyzed C-H activation: L-shaped ligand for para-selective borylation of aromatic esters, Category: esters-buliding-blocks, the publication is Journal of the American Chemical Society (2017), 139(23), 7745-7748, database is CAplus and MEDLINE.
An efficient strategy for the para-selective C-H-borylation of aromatic esters is described, utilizing iridium(I) precatalyst [Ir(cod)(OMe)]2 and an L-shaped ligand I (L1), which enables coordination of the iridium center through its bipyridine moiety and substrate coordination through 2-quinolinol hydrogen bond. For achieving high para-selectivity, a new catalytic system has been developed modifying the core structure of the bipyridine. It has been proposed that the L-shaped ligand is essential to recognize the functionality of the oxygen atom of the ester carbonyl group via noncovalent interaction, which provides an unprecedented controlling factor for para-selective C-H activation/borylation.
