Notes:
Gas-phase ion-molecule reactions of a variety of fluorosilyl carbanions with compounds containing double bonds to oxygen, X=O, have been examined using pulsed ion cyclotron resonance spectroscopy. The predominant reaction channel observed for species not containing acidic hydrogens is a Wittig-like process involving Si—O bond formation and elimination of X=CH2 species. The gas-phase acidity of F3Si(CH3) has been determined and those of F2Si(CH3)2 and FSi(CH3)3 have been estimated. From the fluoride transfer reactions of F3SiCH2- the fluoride affinity of F2Si=CH2 has been estimated and limits on the π bond strength in this silaethene obtained. Potential analytical applications of the Wittig reactivity have been discussed.
