An efficient, regioselective synthesis of fluorine-substituted arylboronic esters was achieved through fluorine-controlled C-H borylation of arenes with diboron catalyzed by a PSiN-platinum complex. The promising utility of the PSiN-platinum catalyst and its unique regioselectivity were demonstrated for the first time, which would complement the well-developed Ir-catalyzed C-H borylation.
Iridium complexes having ap incer-type gallylene ligand were successfully synthesized utilizing bis(phosphino)terpyridine as an efficient scaffold for the IrÀGa I bond. The stabilization of the gallylene moiety by the pincer-type structure enabled various reactions at Ir with keeping the gallylene ligand intact, leading to unique structures and reactivities of PGa I P À Ir complexes.
The synthesis and structural analyses of pincer-type iridium complexes having gallyl- and indyl-metalloligands were achieved utilizing 2,5-bis(6-phosphino-2-pyridyl)pyrrolide as a new scaffold for metal–metal bonds.
Iridium complexes having a pincer‐type gallylene ligand were successfully synthesized utilizing bis(phosphino)terpyridine as an efficient scaffold for the Ir−GaI bond. The stabilization of the gallylene moiety by the pincer‐type structure enabled various reactions at Ir with keeping the gallylene ligand intact, leading to unique structures and reactivities of PGaIP−Ir complexes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
