YieldReaction ConditionsOperation in experiment
With potassium fluoride; dimethyl sulfoxide; Preparing 2-nitrofluorobenzene by Reacting 2-nitrochlorobenzene Using tetrakis(diethylamino)phosphonium bromide as Catalyst A 1.5 l four-necked flask which is equipped with thermometer, anchor stirrer and reflux condenser with bubble counter is charged with 157 g (1 mol) of 2-nitrochlorobenzene, 400 ml of dimethyl sulfoxide (DMSO) (Example 4) or, respectively, 480 ml of tetramethylene sulfone (TMS) (Example 5), 68.4 g (1.2 mol) of potassium fluoride and 3.99 g (0.01 mol) of tetrakis(diethylamino)phosphonium bromide. The reaction mixture is then heated with stirring to the predetermined reaction temperature and is allowed to react for the time indicated. Subsequent workup is as described in Examples 1 and 2.
