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

bidentate NHC-carboxylate ligands were efficiently synthesized and fully characterized including solid-state structures. These unprecedented rhodium(III) complexes demonstrated high selectivity in pyridine-directed ortho-C–H borylation of arenes under mild conditions.
Direct functionalization of the ubiquitous CHbond is receiving much attention because complex structures can be formed from simple precursors. This paper reports a useful method for the direct hydroxylation of 2‐phenylpyridines using palladium(II) chloride and aqueous hydrogen peroxide. In this method, hydrogen peroxide, which has high atom efficiency, is employed as the oxidant and phenol derivatives

Detailed analyses of the 1H and 13C NMR spectra of fifteen mono‐ and di‐substituted isoquinoline derivatives were carried out by two‐dimensional 1H–1H and 1H–13C shift correlation and nuclear Overhauser effect difference techniques.
