Photooxidative Dehydrogenation of Chiral Ir (III) Amino Acid Complexes Based on [Λ-Ir(ppy)₂(MeCN)₂](PF₆)

Inorganics, 2023
Octahedral chiral-at-metal Ir(III) complexes exhibit excellent structural stability and stereoselectivity in asymmetric synthesis. Selectively oxidative dehydrogenation of amino acids could be achieved by exploiting such complexes as chiral templates ...

Experimental data supported techno-economic assessment of the oxidative dehydrogenation of ethane through chemical looping with oxygen uncoupling

, 2021
Ethylene is an essential building block in the petrochemical industry and it is almost exclusively produced via ethane steam cracking, a well-established albeit highly energy and carbon dioxide intensive process.
