Positive ion fast atom bombardment and liquid secondary ion mass spectra of aryl iodonium salts usually contain the intact cation as the base peak in the spectrum, along with lower abundance fragment ions that result from cleavages, rearrangements, and in some cases, combinations of such losses with
Positive-ion fast atom bombardment mass spectra and linked-scan tandem mass spectra were measured for aromatic iodonium salts. The mass spectra usually contain the intact cation of the iodonium salt as the base peak, fragment ions of lower abundance resulting from simple cleavages or rearrangements,
Tbe fast atom bombardment (FAB) mass spectra of telluronium salts were studied. The spectra exhibit the intact cation (C') a d cllster ions (I M + C I '). Tbe principal fragment ions in tbe FAB mass spectra of telluronium salts are IRTel', IR,Tel\*', IR,Te -HI', IRTeRI", a d [RTeR'+ HI+. Wben tbe an
