A wide range of functionalized pyridine ligands were employed to synthesize a variety of Pd(II) complexes [PdL4](NO3)2 and [PdL2Y2], where L = 4-X-py and Y = Cl- or NO3-. Their structures were unambiguously established via anal. and spectroscopic methods in solution (NMR spectroscopy and mass spectrometry) as well as in the solid state (x-ray diffraction). This in-depth characterization showed that the functionalization of ligand mols. with groups of either electron-withdrawing or -donating nature (EWG and EDG) results in significant changes in the physicochem. properties of the desired coordination compounds Downfield shifts of signals in the 1H NMR spectra were observed upon coordination within and across the complex families, clearly indicating the relation between NMR chem. shifts and the ligand basicity as estimated from pKa values. A detailed crystallog. study revealed the operation of a variety of weak interactions, which may be factors explaining aspects of the solution chem. of the complexes. The Pd(II) complexes are efficient and versatile precatalysts in Suzuki-Miyaura and Heck cross-coupling reactions within a scope of structurally distinct substrates, and factors were identified that have contributed to efficiency improvement in both processes. In the experiment, the researchers used many compounds, for example, 4-Acetylpyridine(cas: 1122-54-9Related Products of 1122-54-9)
4-Acetylpyridine(cas: 1122-54-9) belongs to pyridine. Pyridines, quinolines, and isoquinolines have found a function in almost all aspects of organic chemistry. Pyridine has found use as a solvent, base, ligand, functional group, and molecular scaffold. As structural elements, these moieties are potent electron-deficient groups, metal-directing functionalities, fluorophores, and medicinally important pharmacophores. Related Products of 1122-54-9
