The Uses of (PHENYLTHIOMETHYL)TRIMETHYLSILANE
lithio derivative is a one-carbon homologating agent leading to aldehydes via sila-Pummerer rearrangement, vinyl sulfides via Peterson alkenation, and vinylsilanes from silyl epoxides.
Purification Methods
If the sample is suspect, then add H2O, wash it with 10% aqueous NaOH, H2O again, dry (anhydrous CaCl2) and fractionally distil it through a 2ft column packed with glass helices. [Cooper J Am Chem Soc 76 3713 1954.]
