Palladium(II) complexes comprising thiazole-hydrazone Schiff base ligand: Synthesis, structure and catalytic activity in Suzuki-Miyaura coupling reactions
The reaction of PdCl2 and Pd(OAc)2 with (E)-2-(2-(pyridin-2-ylmethylene)hydrazinyl)benzo[d]thiazole (HL) in methanol resulted in the formation of two neutral mononuclear Pd(II) complexes. By using PdCl2 two kinds of crystals with general formula of [Pd(Cl)L]·0.5(C2H5OH) (1a) and [Pd(Cl)L] (1b) were obtained while Pd(OAc)2 gave one type of crystal with general formula of [Pd(OAc)L]·0.5(H2O) (2). These complexes were characterized using spectroscopic methods, and their molecular structures were determined by single crystal X-ray diffraction analysis. In these complexes, the ligand coordinates to the Pd(II) core through the nitrogen atoms of the thiazole ring, pyridine ring, and imine moiety, acting as tridentate mononegative NNN donor ligand. These palladium(II) complexes were also found to exhibit catalytic activity in Suzuki-Miyaura coupling reactions.
期刊介绍：
Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry.
Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
