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
