- Abstract
The catalytic activity of [Pd{CH(CHN(CHPh))} (µ-Br)] complex as an efficient, stable and non-sensitive to air and moisture catalyst was investigated in the Sonogashira cross-coupling reaction under microwave irradiation. In the presence of catalytic amount of this homogeneous catalytic system, various aryl halides were efficiently coupled with phenylacetylene under copper-free conditions. The substituted internal alkynes were produced in excellent yields in short reaction times in NMP at 100 °C. The combination of dimeric complex as homogenous catalyst and microwave irradiation and also NMP as microwave-active polar solvent gave higher yields in shorter reaction times.
