reactions of sulfoxides bearing α-hydrogen(s) (RSOCHR1R2: R-alkyl or aryl; R1, R2 = H, alkyl, or aryl) with Grignardreagents (R3MgBr: R3 = Et, Ph, or vinyl) in the presence of the diisopropylaminomagnesium reagent, generated in situ by the treatment of diisopropylamine with the appropriate Grignardreagents in diethyl ether, have resulted in the formation of the corresponding sulfides (RSCR1R2R3) in moderate
Paris of diastereomeric sulphoximides and sulphilimines of known absolute configuration have been converted into the corresponding carbanions, which have a definite opticalstability.
