Kawamorita, Soichiro published the artcileDirected Ortho Borylation of Functionalized Arenes Catalyzed by a Silica-Supported Compact Phosphine-Iridium System, Recommanded Product: Methyl 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-4-(trifluoromethyl)benzoate, the publication is Journal of the American Chemical Society (2009), 131(14), 5058-5059, database is CAplus and MEDLINE.

An immobilized monophosphine-Ir system, which was prepared in situ from [Ir(OMe)(cod)]₂ and a silica-supported, compact phosphine, showed high activities and selectivities for the borylation of aromatic C-H bonds with bis(pinacolato)diboron. This system was effective not only for the borylation of benzene but also for the ortho borylation of arenes with directing groups, such as ester, amide, sulfonate, acetal, alkoxymethyl, and chloro groups, under mild reaction conditions.

Jiao, Jiao published the artcileA new air-stable Si,S-chelating ligand for Ir-catalyzed directed ortho C-H borylation, Synthetic Route of 1146214-86-9, the publication is Organic & Biomolecular Chemistry (2021), 19(2), 355-359, database is CAplus and MEDLINE.

A new air-stable Si,S-chelating ligand 1-(ⁱPrS)-2-(ⁱPr₂SiH)C₆H₄ (HL) has been developed and used in a directed ortho C-H borylation reaction of aromatic and heterocyclic compounds with B₂pin₂ catalyzed by [Ir(OMe)(cod)]₂/HL combination with a broad substrate scope, providing o-boryl-substituted aromatic and heterocyclic esters, amides and amines. This study provides the first example of using a sulfur-containing ligand in the catalytic C-H borylation process. It provides a rapid, efficient, and economical method for the preparation of organoboron compounds

Auvil, Tyler J. published the artcileInternal lewis acid assisted benzoic acid catalysis, Name: Methyl 2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-4-(trifluoromethyl)benzoate, the publication is Synthesis (2012), 44(14), 2173-2180, database is CAplus.

Internal Lewis acid assisted benzoic acid derivatives are introduced as new low-mol.-weight single-hydrogen-bond donor catalysts for the activation of nitroalkenes. Selected 2-borylbenzoic acid derivatives gave good yields of products in the addition of indoles to nitroalkenes. Control experiments suggest that both the internal Lewis acid coordination and the carboxylic acid functionalities are critical to the optimal performance of these catalysts.
