Maity, Ayan; Anderson, Bryce Lane; Deligonul, Nihal; Gray, Thomas G. published an article in 2013, the title of the article was Room-temperature synthesis of cyclometalated iridium(III) complexes: kinetic isomers and reactive functionalities.Reference of 2-(2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)pyridine And the article contains the following content:

Cyclometalated iridium(III) complexes have been prepared in high yields from base-assisted transmetalation reactions of cis-bis(aquo)iridium(III) complexes with boronated aromatic proligands. Reactions proceed at room temperature Potassium hydroxide and potassium phosphate are effective supporting bases. Kinetic, meridional isomers are isolated because of the mildness of the new technique. Syntheses are faster with KOH, but the gentler base K3PO4 broadens the reaction’s scope. Complexes of chelated ketone, aldehyde, and alc. complexes are reported that bind iridium through formally neutral oxygen and formally anionic carbon. The new complexes luminesce with microsecond-scale(coating) lifetimes at 77 K and nanosecond-scale lifetimes at room temperature; emission quenches in air. Two complexes, an aldehyde and its reduced (alc.) derivative, are crystallog. characterized. Their bonding is examined with d.-functional theory calculations Time-dependent computations suggest that the Franck-Condon triplet states of these complexes have mixed orbital parentage, arising from one-particle transitions that mingle through CI.

On August 4, 2021, Tanaka, Jin; Nagashima, Yuki; Araujo Dias, Antonio Junio; Tanaka, Ken published an article.Formula: C17H20BNO2 The title of the article was Photo-Induced ortho-C-H Borylation of Arenes through In Situ Generation of Rhodium(II) Ate Complexes. And the article contained the following:

Photoinduced in situ “oxidation” of half-sandwich metal complexes to “high-valent” cationic metal complexes has been used to accelerate catalytic reactions. Here, we report the unprecedented photoinduced in situ “reduction” of half-sandwich metal [Rh(III)] complexes to “low-valent” anionic metal [Rh(II)] ate complexes, which facilitate ligand exchange with electron-deficient elements (diboron). This strategy was realized by using a functionalized cyclopentadienyl (CpA3) Rh(III) catalyst we developed, which enabled the basic group-directed room temperature ortho-C-H borylation of arenes. The experimental process involved the reaction of 2-(2-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)pyridine(cas: 1349171-28-3).Formula: C17H20BNO2
