Compounds of formula (IIa): are provided where: X is a group capable of being cleaved from the .alpha.-carbon atom to form an ion of formula (I') C is a carbon atom bearing a single positive charge or a single negative charge; The invention further provides compounds of formula (IIb): where: X is a counter-ion to C. The compounds of formula (IIa) and (IIb) may form ions of formula (I') by either cleaving the C--X bond between X and the .alpha.-carbon atoms in the case of the compounds of formula (IIa) or dissociating X in the case of compounds of formula (IIb).
