摘要

The 1, 2, 3, 4-tetrafluoro-5-halogenobenzenes react with sodium methoxide or dimethylamine with replacement mainly of the fluorine para to the hydrogen. The fluorine para to the halogen is also replaced, and to an extent which increases in the order:(Halogen) Cl< Br< I, but which is always less than the replacement para to the hydrogen. The reactions of the 1, 2, 3, 5-tetrafluoro-4-halogenbenzenes with sodium ...
