ABSTRACT:
A method for making a triarylsulfonium hexafluoro metal or metalloid salt is provided by effecting reaction between a diarylsulfoxide and an aromatic substrate, such as an arylalkylether in the presence of a solution of phosphorus pentoxide and methanesulfonic acid to produce a triarylsulfonium complex. A metathesis of the resulting triarylsulfonium complex is effected with an alkali metal hexafluoro metal or metalloid salt.
