An efficient microwave-assisted suzuki reaction using a new pyridine-pyrazole/Pd(II) species as catalyst in aqueous media

Abstract

A new pyridine-pyrazole N-N ligand has been conveniently synthesized and characterized by 1H-, 13C-NMR, IR spectroscopies, HRMS and X-ray single-crystal crystallography analyses. The ligand adds to palladium(II) under basic conditions to give high yields of an air-stable and water-soluble complex that was fully characterized by NMR and HRMS. The complex was investigated as a catalyst for the Suzuki reaction in aqueous media under microwave irradiation. The compound proved to be an effective catalyst. © 2013 by the authors.
