Per- and Poly-fluorinated Aliphatic Derivatives of the Main-Group Elements 

As in Volumes 1 and 2, no attempt has been made to draw together information on reactions believed to involve transient per- or poly-fluoroaliphatic derivatives of Na, K, Rb, or Cs generated, for example, via attack of the corresponding metal fluorides on fluoro-alkenes or -alkynes. 

Lithium.— Polyfluorocycloalkenyi- and polyfluorobicyclo[2,2,l]heptyl-lithium reagents have featured in work on derivatives of mercury, germanium, tin, phosphorus, and arsenic (see pp. 193, 205, 206, 253, and 265 and mercury and sulphur (see pp. 191, 290, 291, respectively. Perfluoro(tetramethylcyclobutenyl-lithium), dealt
