Özet:
This study contains the synthesis of the novel series of the 2- hydroxyethyl substituted Pd-based N-heterocyclic carbene (NHC) / triphenylphosphine (PPh3) complexes. The (NHC)Pd(II)PPh3 complexes have been prepared from the PPh3 ligand, replaced by 3-chloro pyridine ligand in (NHC)Pd(II)(3-Cl-pyridine) complexes. The novel 2-hydroxyethyl substituted (NHC)Pd(II)PPh3 complexes have been characterized by using 1H NMR, 13C {1H}NMR, 31P {1H}NMR, FTIR spectroscopy, and elemental analysis techniques. Molecular and crystal structure of 1 f was obtained by using single-crystal X-ray diffraction method. The novel 2-hydroxyethyl substituted (NHC)Pd(II)PPh3 complexes have been examined as catalysts in the Sonogashira cross-coupling reactions aqueous medium and demonstrated excellent activity in this reaction. © 2018 Wiley-VCH Verlag GmbH & Co.
