The catalytic activity of the complex was tested in Suzuki coupling reactions for synthesis of biaryls containing various substrates. The identifications of the biarlys were performed by H-1 NMR and GC-MS. The catalytic activity tests revealed that high selectivity was achieved with a small addition of the catalyst. Moreover by-product formation was not observed in the spectra of H-1 NMR and GC-MS. Mercury poisoning and leaching test confirmed that the catalyst has heterogeneous character. The reusability tests showed that the catalyst did not lose its activity after six runs. (C) 2015 Elsevier B.V.
