A sulfoxonium metathesis reaction between TMSOI and cost-effective DMSO-d6 provides deuterated trimethylsulfoxonium iodide (TDMSOI). Subsequent "one-pot" trideuteromethylation installs the -CD3 moiety into broad functionalities including phenols, thiophenols, acidic amines, and enolizable methylene units in high yield and at a useful level of deuteration.
