Streszczenie

A series of 13 new PEPPSI-type complexes with small NHC ligands and differently substituted imidazoleswere prepared using as substrates [Pd(m-X)X(bmim-y)]2dimer or imidazole complexes PdCl2(imida-zole)2. Improvement of the synthetic method allowed simplification of the purification step. The ob-tained complexes efficiently catalyzed the Suzuki-Miyaura cross-coupling of substituted bromobenzenesand arylboronic acids in water and iniPrOH/water mixture. The observed catalytic activity was signifi-cantly better than that of Pd(OAc)2and similar to that of Pd(IPr)Cl2(3-Cl-py) in the same conditions. TEManalysis of the post-reaction mixture evidenced formation of Pd NPs of diameter ca. 3 nm, participatingin the catalytic process.
