title: PdCl2(dppf)-catalyzed in situ coupling of 2-hydroxypyridines with aryl boronic acids mediated by PyBroP and the one-pot chemo- and regioselective construction of two distinct aryl-aryl bonds.
abstract: We present a PdCl(2)(dppf)-catalyzed synthesis of 2-arylated pyridine derivatives via the in situ coupling of 2-OH pyridines and boronic acids mediated by PyBroP. In addition, the highly chemo- and regioselective construction of two different aryl-aryl bonds via a one-pot operation has also been demonstrated by the orthogonal use of this method with the Ni-catalyzed Suzuki-Miyaura coupling of phenols.
