Notes:
The positive-ion fast atom bombardment (FAB) mass spectra of stibonium salts have been studied. The spectra exhibit an abundant intact cation (C+) and fragment ions resulting from the loss of R, R′ or stable neutral species from the cation. The principal fragment ions in the FAB mass spectra of stibonium salts are [R3Sb]+·, [R2Sb]+, [R2SbH2]+, [RSbR′]+, [RSbH]+, [RSb - H]+ and [R2SbR']+·. In most cases, [ M + C] + cluster ions were detected. When the anion was bromine, the adduct ions [M + (R - H)Sb]+, [C + (R-H)]+ and [ C + (R′ - H)]+ were also observed, whereas when the anion was [BPh4]-, interesting cluster ions such as [M + (BR′ - H)]+ and [M + (BR′ - 3H)]+ appeared.
