Ligands play an important role in coordination chemistry. Earlier this month, Alfa Chemistry revealed that the company had started the offering of three types of ligands, namely, oxygen-donor ligands, nitrogen-donor ligands, and carbon-donor ligands, for researchers worldwide.
With the appropriate choice and design of ligands, metal complexes can achieve different properties and functions. Owing to their great application potential, ligands and their complexes have been widely used in fields like industrial production, energy development, biochemistry, and analytical chemistry.
Oxygen-Donor Ligands
Oxygen-donor ligands refer to ligands that contain oxygen moieties, such as the carbonyl group, hydroxyl group, and ether bond. Oxygen-donor ligands can form complexes with various metals, including but not limited to transition metals, alkaline earth metals, and rare earth metals, which are widely used in catalysis, luminescence, and medicinal fields. Currently, Alfa Chemistry offers all kinds of oxygen-donor ligands, covering diketone ligands, BINOL ligands, crown ligands, as well as BIPHEN and TADDOL ligands for customer selection.
Nitrogen-Donor Ligands
Nitrogen-donor ligand is a ligand that provides nitrogen, in which nitrogen is both an electron donor atom and a good coordination group. As for now, nitrogen-donor ligands are among the most successful, versatile, and commonly used ligands and have been widely used in fields like industrial catalysis, medicine, and separation science. Alfa Chemistry can now provides different types of nitrogen-donor ligands, including: chiral nitrogen-donor ligands, achiral nitrogen-donor ligands, monodentate, bidentate, as well as tridentate and polydentate nitrogen-donor ligands.
Carbon-Donor Ligands
Carbon-donor ligands are ligands that contribute to carbon atoms in chemical reactions. In most cases, they are also referred to as carbene ligands. N-Heterocyclic carbenes are viewed as the most versatile carbon-donor ligands in transition metal and organometallic catalysis. Some carbon-donor ligands provided by Alfa Chemistry include: t-Butylmethylacetylene (CAS 999-78-0), 1,3-Di-tert-butylimidazol-2-ylidene (CAS 157197-53-0), 2-Chloro-1,3-bis(2,6-diisopropylphenyl)-1H-imidazolium Chloride (CAS 1228185-09-8), (1,3-Dimethyl-1H-imidazol-3-ium-2-yl)trihydroborate (CAS 1211417-77-4), 1,4-Dimethyl-1,2,4-triazolium Iodide (CAS 120317-69-3), 1,3-Di(1-adamantyl)imidazoliniumTetrafluoroborate (CAS 1176202-63-3), 1,3-Dimethylimidazolium Chloride (CAS 79917-88-7), etc.
“As a global leader in the field of coordination chemistry, we are committed to providing comprehensive and high-quality ligands and coordination complexes for our global customers. Meanwhile, we also offer services and technologies, including: analysis and testing, custom synthesis, project design, and precious metals recovery, to support business in various fields,” said one of the senior scientists from Alfa Chemistry.
