Phosphoric amides. 7—Mass spectrometry of phosphoric amido esters: Fragmentation patterns and migratory aptitudes
摘要:
AbstractMass spectra of 38 organophosphorus compounds, containing both phosphate ester (P(O)OR) and phosphoramidate (P(O)NR′R″) functional groups, were recorded and discussed. Attention was focused on PN bond cleavage, which can involve simple fission, fission accompanied by hydrogen migration from the ester group and fission accompanied by the migration of the ester R group to the departing nitrogen atom. Fragmentations characteristic for the N(β‐chloroethyl) derivatives (phosphorylated nitrogen mustards) are also presented.
