The negative ion mass spectra of p ‐nitrobenzoyl derivatives of amino esters show pronounced molecular anions and characteristic fragmentation patterns. Fragment anions observed in the spectra of o ‐nitrobenzoyl analogues arise by various interactions between the nitro and amino ester groups. No fragmentation of the amino ester residue is observed for the m ‐nitrobenzoyl derivatives, but the +E spectra of these systems can be used to provide definitive structural information.
