Methanesulfinic acid sodium salt is used in the preparation of alkyl methyl sulfone and methyl bis(4-tolyl)sulfoniumtrifluoromethanesulfonate. It is also employed in the synthesis of two sulfonyl type reversible addition-fragmentation transfer (RAFT) agents such as benzyl methylsulfonyldithioformate and benzyl phenylsulfonyldithioformate.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

RUO – Research Use Only
Nucleophilic reagent for preparation of alkyl methyl sulfones: J. Am. Chem. Soc., 75, 5582 (1953). Aryl methyl sulfones are formed by SNAr displacement of activated p-fluoro or p-chloro substituents from aryl aldehydes, ketones, nitriles or nitro compounds in DMSO: J. Org. Chem., 54, 4691 (1989). In the presence of CuI in DMF, displacement of non-activated iodoarenes occurs: Tetrahedron Lett., 36, 6239 (1995); see also: J. Org. Chem., 70, 2696 (2005). Under similar conditions, selective displacement of an aryl bromo substituent in the presence of an aryl fluoro can be effected.: J. Org. Chem., 70, 268 (2005). Arylboronic acids undergo displacement with the reagent under mild conditions in the presence of copper(II) acetate in DMF or DMSO; selective displacement of the boronate group from 3-bromobenzeneboronic acid is possible: Tetrahedron Lett., 45, 3233 (2004).
