Abstract |
: |
New complexes of palladium metal containing mixing donor ligands (PR3), maleonitriledithiolate (MNT) have been synthesized and also 4,4’-(tbut)-2,2’-bipyridine with MNT have been synthesized. These complexes were characterized by X-ray single crystals to determent the structure geometry. Besides that, we studied the spectroscopic of these complexes by UV-Vis to see the most transitions in each complex and compare them with the DFT calculation result. In addition, the complexes were employed in Suzuki cross coupling reactions under mild condition for the first time and shows good to excellent activity for the coupling.
Phosphorus ligands also facilitate the formation of bulky electron-rich complexes. Phosphorus donor atoms have the ability to improve the catalytic activity when used to form transition metal complexes. However, over time, its extreme sensitivity to air and moisture has been a thing of concern to chemist.
Nitrogen donor ligands are seeing to be promising and could serve as a good alternative to the phosphorus donor atoms. Pyridine heterocyclic compound synthesis continues to attract much attention due to their verse applicability on various fields including Pharmaceutical and organic synthesis. In the pharmaceutical industries, transition metals such as palladium and copper complexes have been used successfully for the preparation of very active hypertensive drugs and researches are continually being carried out to explore more areas where these materials (Palladium catalysts) can be applied.
MNT ligand has unique properties, the dithiolate complexes have unusual redox properties. As Metal maleonitriledithiolate (MNT) complexes have large molar absorptivities and observed in the UV-Vis spectra are very sensitive to the extent of back bonding present from the metal.
