Abstract The configurational stability of some sulfurated styrene oxides has been investigated. Chemical studies have shown that in THF at 157 K α-lithiated ortho-and para- phenylthiostyrene oxides are configurationally unstable and undergo a fast racemization on the time scale of the reaction, whereas α-lithiated meta-phenylthiostyrene oxide retains its stereochemical integrity for at least 60 min. The deprotonation-trapping methodology has ...
