Reaction of RfI (RfC6F13 or C8F17) with Cd powder in DMF at room temperature under N2 afforded RfCdX (XI or Rf) in moderate (48–52%) yield. Although no reaction was observed with Cd powder and RfI (RfC6F13 or C8F17) in CH3CN at room temperature, reaction at reflux gave the homocoupled products C6F13C6F13 (67%) and C8F17C8F17 (61%), respectively. No F-alkylcadmium reagent was detected by 19F NMR
