摘要：

Benzene was electrochemically fluorinated at platinum anode at 2.5 V [vs. Ag/Ag+ (0.01 mol/dm3)] in acetonitrile solutions containing R4NF . nHF (R=CH3, C2H5, n-C3H7 and n-C4H9, n = 2, 3 and 4) and (C2H5)3N . 3HF, as supporting electrolytes and fluorine sources. The present electrolyte solution systems were mild and suitable for the fluorination of benzene. The yields of fluorobenzenes were in the range of 20-45%. The current density during the macro-electrolysis. ie the reaction rate, was significantly varied with the composition of the electrolyte solution.
