Carbon−Carbon Formation via Ni-Catalyzed Suzuki−Miyaura Coupling through C−CN Bond Cleavage of Aryl Nitrile
摘要:
The Suzuki-Miyaura coupling of aryl nitriles with aryl/alkenyl boronic esters is reported. With this method, the cyano group could be applied as a protecting group of arenes and finally as a leaving group to further construct polyaryl scaffolds.

Working together: A new approach of mutualactivation between naphtholates and aryl boronic acid derivatives by the formation of borates to facilitate the Suzuki–Miyauracouplingthroughdirectcleavage of the sp2CObond by nickel catalysis is described (see scheme; R′: annulated ring system). Various naphtholates and aryl boronic acid derivatives could be directly coupled in good yields.

A pyrene-based compound and an organic light-emitting diode including the pyrene-based compound are provided. The pyrene-based compound of Formula 1 above may emit blue light having high color purity. For example, an organic light-emitting diode including the pyrene-based compounds of the invention may emit blue light having a y coordinate with a color purity of 0.1 or less, for example, a color purity of 0.09 or less, which is near to the NTSC or sRGB specification. A thin film including the pyrene-based compounds of the invention may be highly amorphous, and thus may have improved electrical stability. Accordingly, an organic light-emitting diode including the pyrene-based compounds of the invention may have improved lifetime characteristics.
