The tetrakis(triphenylphosphine)palladium(O)-catalyzed coupling of benzeneboronic acid with 2-chloro, 6-bromo and 6-bromo-2-chloro derivatives of 1- and 3-methylimidazo[4,5-b]pyridines to novel 2-phenyl-, 6-phenyl- and 2,6-diphenylimidazo[4,5-b]pyridines is described. The phenylation of imidazo[4,5-b]-pyridines containing labile hydrogens was not successful.
四(三苯基膦)钯(O)催化的苯硼酸与1-和3-甲基咪唑并[4,5- b ]吡啶的2-氯,6-溴和6-溴-2-氯衍生物偶联至新型2描述了-苯基-,6-苯基-和2,6-二苯基咪唑并[4,5- b ]吡啶。含不稳定氢的咪唑并[4,5- b ]-吡啶的苯基化作用不成功。
