Abstract:
The efficient conversion of carbon dioxide (CO2) into valuable products remains a keystone of sustainable energy research. Achieving this goal requires catalytic methodologies that can adapt to diverse energy sources such as light, heat, or electricity. This concept highlights the remarkable versatility of tetradentate PNNP-ligated iridium complexes, (PNNP)Ir, as multifunctional catalysts, which demonstrate outstanding performance in CO2 reduction across photochemical, thermal, and electrochemical systems. By fine-tuning the ligand structure for each system, (PNNP)Ir complexes achieved remarkable efficiency, selectivity, and durability across all applications.

02:24Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
02:51Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
