Abstract
Monomeric and polymeric triarylsulfonium complex salts which may be prepared by contacting diarylsulfoxides or polymeric arylsulfoxides with aromatic compounds in the presence of an organosulfonic acid are described. An example is tris-(4-phenoxyphenyl)sulfonium methane sulfonate prepared by reaction of bis-(4-phenoxyphenyl)sulfoxide, diphenyl ether and methane sulfonic acid. The compounds demonstrate useful corrosion inhibiting properties.
