Copper promoted CN and CO bond cross-coupling with phenyl and pyridylboronates
摘要:
Acyclic and cyclic esters, as well as anhydride (boroxine) of phenylboronic acids are efficient phenylating agents in copper promoted C-N and C-O bond cross-coupling reactions. The first successful C-N cross-coupling of a heterocyclic boronate with heteroarenes, such as indazole, has been demonstrated. (C) 2003 Elsevier Science Ltd. All rights reserved.

The present invention discloses a phosphorescent tris-chelated transition metal complex comprising i) two identical carbon-nitrogen (ĈN) or nitrogen-nitrogen (N̂N) chromophoric ligands being incorporated into a coordination sphere thereof with a transition metal, and one carbon-phosphorus (ĈP) chelate being incorporated into the coordination sphere; or ii) one carbon-nitrogen (ĈN) or nitrogen-nitrogen (N̂N) chromophoric ligand forming a coordination sphere thereof with a transition metal, and two identical carbon-phosphorus (ĈP) chelates being incorporated into the coordination sphere, wherein the metal is iridium, platinum, osmium or ruthenium, and the chromophoric ligands possess a relatively lower energy gap in comparison with that of the non-chromophoric chelate, the latter afforded an effective barrier for inhibiting the ligand-to-ligand charge transfer process, so that bright phosphorescence can be observed. The architecture and energy gap of the present molecular designs are suitable for generation of high efficiency blue, green and even red emissions.
