実験手順

2020 g (10.5 mol) of 2,5-dichloronitrobenzene, 70 g (0.2 mol) of octadecyltrimethylammonium chloride and 580 g (10.0 mol) of potassium fluoride were reacted analogously to Example 1. 936 g (72.3%, relative to 2,5-dichloronitrobenzene converted) of 2-fluoro-5-chloronitrobenzene and 600 g (29.7%, relative to 2,5-dichloronitrobenzene employed) of unreacted 2,5-dichloronitrobenzene were obtained.
