Carbyne chemistry
WebMar 6, 2024 · Transition metal carbyne complexes are organometallic compounds with a triple bond between carbon and the transition metal. [1] This triple bond consists of a σ-bond and two π-bonds. [2] The HOMO of the carbyne ligand interacts with the LUMO of the metal to create the σ-bond. The two π-bonds are formed when the two HOMO orbitals of the ... WebScheme 1. Synthesis of diiron μ-aminocarbyne complexes with isocyanate and isothiocyanate as the terminal ligands and S -methylation reaction. Xyl = 2,6-C 6 H 3 Me 2 . Here, we extended the chemistry of diiron aminocarbyne complexes with pseudohalide ligands, including reactions with a selenocyanate source.
