N-n bond cleavage
WebJun 16, 2024 · Transition-metal-catalyzed decarbonylation via carbon–carbon bond cleavage is an essential synthetic methodology. Given the ubiquity of carbonyl compounds, the selective decarbonylative process offers a distinct synthetic strategy using carbonyl groups as “traceless handles”. This reaction has been significantly developed in recent … WebIn chemistry, bond cleavage, or bond fission, is the splitting of chemical bonds. This can be generally referred to as dissociation when a molecule is cleaved into two or more …
