摘要：
The reactions of Zn(CF3)Br . 2 CH3CN, Cd(CF3)(2) . 2 CH3CN or Bi(CF3)3/AlCl3 with tertiary amines lead to the formation of quaternary ammonium salts of the general formula [R3NCF2H]X. The reaction of 4-N,N-dimethylaminopyridine with Zn(CF3)Br . 2 CH3CN yields (N-difluoromethyl)-4-N,N-dimethylaminopyridinium bromide. Bi(CF3)(3)/AlCl3 reacts with 1,4-diazabicyclo[2.2.2]octane to form a mixture of mono- and bis(difluoromethylammonium) salts.
