    Author: Ban I, Sudo T, Taniguchi T, Itami K.
    Journal: Org Lett; 2008 Aug 21; 10(16):3607-9. PubMed ID: 18613691.
    Abstract:
    A new copper-mediated cross-coupling of arenes and arylboronic acids is described. Under the influence of Cu(OCOCF 3) 2, the C-H bond arylation of electron-rich arenes with arylboronic acids takes place to afford a range of biaryls in good yields. The reaction is selective for cross-coupling; no homocoupling product arising from arenes or arylboronic acids is detected. Multiple C-H bond arylation is possible with indoles and pyrroles furnishing interesting extended pi-systems.
