WebTransition metals of coordination complexes that contain carbon monoxide ligands are known as metal carbonyls. Metal carbonyls are transition metal-carbon monoxide complexes with a metal-carbon link. Furthermore, in metal carbonyl, both σ (sigma) bonds and π (pi) bonds are possessed by the metal-carbon bond. The ligand to the metal is a σ ... WebMar 13, 2024 · In the recent years, transition-metal-free intra- or intermolecular oxidative C(sp 3)-H amination has upsurged as a significant approach for the direct C-N bond formation . Moreover, cost-effectiveness, step economy, and less toxicity are the benefits associated with this strategy.
