The introduction of electronegative substituents onto the silyl group of triaryl(2-silylethylidene)phosphorane promotes eliminative silyl migration relative to the Wittig reaction; the combination of this effect with modification of the phosphorane substituents leads to highly diastereoselective reagents for alkenylation.
UNUSUAL REACTION OF 2-TRIMETHYLSILYLETHYLIDENETRIARYLPHOSPHORANES (SEYFERTH-WITTIG REAGENT) WITH α-METHYLALDEHYDES: A NOVEL METHOD FOR HIGHLY CRAM-DIASTEREOSELECTIVE ADDITION OF VINYL ANION EQUIVALENT

By the reaction of α-methylaldehydes with trimethylsilylethylidenetriarylphosphoranes the introduction of vinyl group is effected in highly Cram-selective manner.
