The process of reacting dithiolium compounds with an hydroxy compound such as water, alcohols, etc., under basic conditons so as to substitute the hydroxy constituent into the 3 or 5 position of the thiolium ring thus replacing the positive ionic valency with a covalent bond; and to the dithiole compositions formed and uses therefor, for example as corrosion inhibitors, etc. The process can be reversed to reform the original dithiolium compounds by reacting the dithiole compound under acidic conditions. The reactions may be summarized by the following reaction: ##STR1##
