The stereoselective reduction of acetylenic sulfones to cis vinylic sulfones was effected by using a novel reduction system consisting of copper(II) salts (Cu(BF4)2, Cu(OTf)2, CuF2, etc.) and a hydrosilane. The best result was obtained by the use of Cu(BF4)2. A divalent copper hydride is proposed to be responsible for this reduction.

(Chemical Equation Presented) Often elusive, trisubstituted (Z)-1-alkenyl phosphonates can be prepared by the semihydrogenation of allenyl phosphonates in the presence of Pd complex 1. This reaction, which occurs in high yield with high chemo-, regio-, an
Stereoselective preparation of vinyl sulfones by protodesilylation of allyl silanes

Allyl sulfones can be conjugated to furnish vinyl sulfones via allyl silane intermediates. The stereoselectivity observed in the protodesilylation step provides a new method for stereoselective preparation of (E)-di-and tri substituted vinyl sulfones.
Structure-Stability Relationships in Unsaturated Sulfur Compounds. III. A Thermodynamic and 13C MNR Spectroscopic Study of the Conformations of Vinyl Sulfones
Kimmelma, Reijo
, p. 1201 - 1206 (2007/10/02)
The conformations of the stable rotamers of alkyl 1-propenyl sulfones have been studied in a thermodynamic and 13C NMR spectroscopic study.The most stable rotamer of the E isomer was found to have the anticlinal conformation.The Z isomer will probably adopt a nearly anticlinal conformation.
