Stereoselective synthesis of racemic and optically active E-vinyl and E- dienyl sulfoxides via Wittig reaction of α-sulfinyl phosphonium ylides

A series of α-sulfinyl phosphonium ylides have been obtained in the reaction of phosphonium mono- and diylides with sulfinic acid esters. The use of (-)-(S)-menthyl p-toluenesulfinate in this reaction afforded the corresponding (S)-((p-tolylsulfinyl)methyl)triphenylphosphonium ylide. The Wittig reaction of these ylides with saturated and unsaturated aldehydes resulted in the formation of racemic and optically active (+)-(R)-vinyl and dienyl sulfoxides with the E-geometry. The synthesis of (+)-(R)-((p- tolylsulfinyl)methyl)triphenylphosphonium iodide as a precursor of the optically active ylide has also been described.

Phosphinosulphoxide rhodium complexes. Synthesis, crystal structure, and catalytic chemistry of -hepta-2,5-diene>rhodium(I)trifluoromethanesulphonate and asymmetric analogues

α-Phosphinosulphoxides are readly accessible by the reaction of α-lithioalkylsulphoxides with Ph2PCl, and are stable towards internal oxygen transfer when pure.The compound Ph2PCH2S(O)Ph thus prepared was shown to form a cationic rhodium bicyclohep
