摘要：
The catalytic activity of ortho-palladated [Pd{C6H2(CH2CH2NH2)-(OMe)2,3,4}(m-Br)]2, a complex of homoveratrylamine in the copper-free Sonogashira coupling reaction has been investigated. This complex is a catalyst that is efficient, stable and non-sensitive to air and moisture in the Sonogashira reaction. In this homogeneous catalytic system, various aryl halides were efficiently coupled with phenylacetylene in mostly moderate to good yields in N-methylpyrrolidone at 100?degrees C under copper-free conditions.
