We have developed Friedel–Crafts (FC) sulfonylation of aromaticcompounds with methyl p-toluenesulfonate as a sulfonylating precursor. In this procedure, methyl p-toluenesulfonate was treated and activated with pyridine to produce N-methylpyridinium p-toluenesulfonate as a sulfonylation reagent. Reactivity of this salt for the sulfonylation of mesitylene was investigated in the presence of three different

The crystal structures of bis-pyridine stabilized iodine dications [PhI(pyr)2]2+ are reported as triflate salts, representing the first ligand supported iodine dications to be structurally characterized. The pyridine complexes are susceptible to ligand exchange in reaction with stronger N-based donors such as 4-dimethylaminopyridine. Attempts to extend this reactivity to N-heterocyclic carbene and
