ABSTRACT:
Triarylsulfonium polyfluoro metal or metalloid salts are provided by effecting the oxidation of a diarylsulfide, while under dehydrating conditions, in the presence of a strong protonic acid. The resulting triarylsulfonium acid salt can thereafter be directly metathesized with an alkali metal or alkaline earth metal polyhalo salt.
These compounds have the general formula ##STR1## where Q is selected from .dbd.S.fwdarw.O, --S-- and mixtures thereof, M is a transition metal or metalloid, "c" is an integer of 1 to 3, "d" is an integer of 0 to 3, R.sup.6 is phenyl or naphthyl, R.sup.7 is phenylene or naphthalene optionally substituted with one or more radicals selected from the class consisting of --CH.sub.3, --OCH.sub.3, --CO.sub.2 H, --Br, --Cl, and NO.sub.2.
