PART 17: AROMATIC AMIDES (MASS SPECTRUM FRAGMENTATION PATTERN) FOR CSIR NET/GATE/M.Sc

For aromatic amides a resonance-stabilized benzoyl cation is formed, and this may undergo further cleavage of CO loss leading to a phenyl cation. If amides having gama hydrogen McLafferty rearrangement and lead frequently to the N–CO α-cleavage due to conjugation of the α,β-unsaturated carbonyl group of the amide #ACETINALIDE #MCLAFFERTY #PHENYLCATION
