Abstract
The enzyme catalyzed displacement of the methyl sulfonyl group from pentachlorophenyl methyl sulfone, the m-chloroperoxybenzoic acid oxidation of methyl mercaptan and the reaction of methyllithium with sulfur dioxide are methods described for the synthesis of isotopically labeled methanesulfinic acid. The first two methods can be carried out on a milligram scale and are suitable for high specific activity preparations while the latter method is suitable for preparations on a gram scale. Conditions are also given for the preparation of isotopically labeled methanesulfonic acid.
