  N-fluoropyridinium salts were found to react with Wittig reagents containing electron-withdrawing groups to give olefins in 47–83% yield. The mechanism of this conversion is believed to involve single-electron transfer from Wittig reagent to N-fluoropyridinium cation.

  acylmethylene triphenylarsoranes, the first stable α-thiyl arsonium ylides, are prepared by phenylsulfenylation–transylidation reaction of the corresponding acylmethylene triphenylarsoranes with phenylsulfenyl chloride; Wittig reactions are carried out under mild reaction conditions on the arsonium ylides to provide α-phenylthio-α,β-unsaturated ketones.
