  摘要：

  The selective alkylation of functionalized 2-(1H-imidazol-1-yl)pyridines 1 furnishes 3-methyl-1-pyridinyl-1H-imidazolium salts 2, which can be deprotonated to deliver strongly electron-donating bidentate N-heterocyclic carbene ligands (NHC). The synthesis of these ligands and their application in the iridium-catalyzed C H activated borylation of arenes with its current scope and limitations are reported. (C) 2010 Elsevier Ltd.

  A platinum complex having at least one carbene fragment, and an OLED using the same are described. The platinum complex contains a platinum cation, a zero-valent nitrogen-containing heterocyclic bidentate chelate, and a dianionic nitrogen-containing heterocyclic bidentate chelate. The zero-valent nitrogen-containing heterocyclic bidentate chelate has at least one carbene unit coordinating to platinum. The dianionic nitrogen-containing heterocyclic bidentate chelate has at least one electron-withdrawing substituent, and forms two N—Pt bonds, or one N—Pt bond and one C—Pt bond, with the central platinum cation.
