WebMar 16, 2024 · Transition-metal-catalyzed C-H functionalization has emerged as a shortened synthetic sequence in recent years for the construction of C-C/C-hetero bonds (Ye and Cramer, 2015). However, the presence of a nearby directing group is generally needed to direct the position of a metal catalyst for specific C-H bond activation. 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 ...
