This study contains the synthesis of the 2-hydroxyethyl-substituted Pd-PEPPSI complexes and their catalytic activity in the Suzuki-Miyaura reaction aryl chlorides in aqueous media. The Pd-PEPPSI complexes have been prepared from the 2- hydroxyethyl-substituted N-heterocyclic carbene (NHC) precursors, palladium chloride and 3-chloropyridine. The Pd-PEPPSI complexes have been characterized by using (HNMR)-H-1, (CNMR)-C-13, FTIR spectroscopy and elemental analysis techniques. The Pd-PEPPSI complexes have been examined as catalysts in the Suzuki-Miyaura reactions in aqueous media with arylboronic acid derivatives. Also, they have demonstrated excellent activity in these reactions. Molecular and crystal structure of one of the 2-hydroxyethyl substituted Pd-PEPPSI complex was determined by single crystal X-ray diffraction method. X-ray studies show that the molecular structure adopts a slightly distorted square-planar geometry with the palladium (II) center.eninfo:eu-repo/semantics/closedAccessN-Heterocyclic carbenesPd-PEPPSI complexesPhenylboronic acidSuzuki-Miyaura reactionX-ray diffractionArticle3359974998010.1002/slct.2018020462-s2.0-85053614228Q2WOS:000445178600002Q3
