Descripción general

Rhenium is a very hard, corrosion, and wear-resistant rare metal with ahigh atomic number. It is widely used in the field of catalysis and the preparationof alloys for jet engines.

Aplicación

Rhenium can be used as a working electrode for electrochemical hydrogen evolution reactions.

It can be used as an additive to prepare a molybdenum-titanium-zirconium (TZM) alloy joint to improve its tensile strength.

It can also be used as a catalyst for various hydrodeoxygenation reactions.

The viability of the Huisgen cycloaddition reaction for clickable radiopharmaceutical probes was explored with an alkyne-functionalized 2-[(pyridin-2-ylmethyl)amino]acetic acid (PMAA) ligand system, 3, and fac-[M(I)(OH2)3(CO)3](+) (M = Re, (99m)Tc). Two synthetic strategies, (1) click, then chelate and (2) chelate, then click

New cationic metallo ligands L1-L3 based on bis(terpyridine) ruthenium(II) complexes decorated with differently substituted 2,2'-bipyridines attached via amide groups (5-NHCO-bpy, 4-CONH-bpy, 5-CONH-bpy) were prepared. Coordination of Re(I)Cl(CO)(3) fragments to the bpy unit gives the corresponding bimetallic Ru~Re complexes 1-3. Hydrogen
