Abstract
A direct trideuteromethylation of sulfenate ions derived in situ from β-sulfinyl esters in the presence of a base utilizing inexpensive CD3OTs as the electrophilic trideuteromethylating agent provides an array of trideuteromethyl sulfoxides in very good yields with a high degree of deuteration. Trideuteromethyl sulfoxides can be readily modified into trideuteromethyl sulfones and sulfoximines.
