Allgemeine Beschreibung

Methyl p-tolyl sulfoxide (MTSO), an alkyl-substituted p-tolyl sulfoxide, is a Lewis base. It behaves as an activator of silicon tetrachloride that is employed in aza-Diels-Alder reaction.

Anwendung

Methyl p-tolyl sulfoxide may be used as a catalyst in the preparation of homoallylic alcohols by the allylation of aldehydes with allyltrichlorosilane. It may be used as a ligand in the synthesis of molybdenum chlorocomplexes.

Production of reactive oxygen species represents a fundamental innate defense against microbes in a diversity of host organisms. Oxidative stress, amongst others, converts peptidyl and free methionine to a mixture of methionine-S- (Met-S-SO) and methionine-R-sulfoxides (Met-R-SO). To cope with such
