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 synthetic utility of these novel reagents is described.
