2,3-Dichloronitrobenzene → 1-Chloro-2-fluoro-3-nitrobenzene

Participants

Reaction Conditions

Reaction Steps

57.6 g (0.3 mol) of 2,3-dichloronitrobenzene and 13.9 g (0.24 mol) of potassium fluoride were introduced into a 100 ml flange flask and fitted with a reflux condenser and blade stirrer and stirred at 150° C. for 2 hours (no reaction). The reaction suspension was heated to 190° C. and stirred for a further 4 hours at this temperature. Amount of 3-chloro-2-fluoronitrobenzene formed: after 2 hours: 1 GC area-%. after 8 hours: 8 GC area-%.
