WebJul 23, 2015 · A nickel-NHC catalyst grabs a normally unreactive amide and pulls apart its C–N bond. The oxidative addition transition state at top is shown just at the point when the C–N bond (red) is breaking. WebFeb 1, 2024 · The double bond character of the C-N bond results in a relatively short bond (1.32 angstroms vs. the normal length of a pure C-N bond, 1.47 angstroms). The double bond resonance form of the peptide bond helps to increase stability and decrease rotation about that bond. The partial double bond character is either strengthened or weakened ...
