摘要：

Readily available NCN-pincer palladium complexes comprising two pyrazole units as the source of both N-donor atoms are successfully employed as catalysts in a range of C-C bond-forming reactions. Good to excellent results are obtained in all cases regardless of the electronic nature of the substrates, along with more convenient procedures and comparatively much lower catalysts loadings in Suzuki and Sonogashira couplings. This paper presents the first report of a Sonogashira coupling reaction by means of a NCN catalyst.
