Synthesis
Commercially available bis(methylthio)methane is deprotonated by n-Butyllithium in THF/hexane at -60 to 0 °C. The resulting lithio derivative is quenched at -40 °C with 1 equiv of Chlorotrimethylstannane. An aqueous workup followed by vacuum distillation affords the bis(methylthio)(trimethylstannyl)methane reagent in 82% yield.[1] The analogous Bis(methylthio)(trimethylsilyl)methane can be prepared by a similar procedure.[2]
