Electron impact mass spectral interpretation for some thiophosphoryl-p-acetylaminobenzenesulfonamides
This work discusses the synthesis and the fragmentation patterns for 2‐(p‐acetylaminosulfonamido)‐2‐thiono‐(5,5‐dimethyl‐1,3,2‐dioxaphosphorinane)(1) and for the p‐acetylaminosulfonylamides of O,O‐diethylthiophosphoric acid (2), O,O‐diphenylthiophosphoric acid (3), dimethylaminocyclohexylthiophospho...

Summary: | This work discusses the synthesis and the fragmentation patterns for 2‐(p‐acetylaminosulfonamido)‐2‐thiono‐(5,5‐dimethyl‐1,3,2‐dioxaphosphorinane)(1) and for the p‐acetylaminosulfonylamides of O,O‐diethylthiophosphoric acid (2), O,O‐diphenylthiophosphoric acid (3), dimethylaminocyclohexylthiophosphoric acid (4), and diethylaminophenylthiophosphoric acid (5). A thionamidic‐thiolimidic structure was attributed to compounds 1–5, consistent with their IR and NMR spectra. EI mass spectra at 70 eV, high resolution (HR) mass measurements and metastable ion spectra were used to elucidate the fragmentation processes and to determine the kinetic energy release values associated with the metastable ion dissociations. HR accurate mass measurements were used to confirm the compositions of the more abundant ions. Copyright © 2001 John Wiley & Sons, Ltd. |
