Metal dehalogenation of bromodifluoromethyltriphenylphosphonium bromide with Cd, Zn, or Hg provides a practical route to fluoroolefins that contain an allylic halogen or a pentafluorophenyl group. No SN2′ or ring substituted products are observed.

fluorohalomethanes provides a rapid and high yield synthesis of various types of fluorinated phosphonium salts, bis-phosphonium salts and phosphoranium salts. These salts are useful precursors to fluorine-containing ylides, carbenes and methide ions. Examples of the preparation, mechanism of formation, and syntheticutility of these novel reagents is described.
