Description and Uses

2-Chloro-4-fluorobenzonitrile is an organohalogen compound that can be used for aryl dechlorination and defluorination reactions using organic super photoreductants. The use of a light emitting diode to directly excite the super electron donor tetrakis(dimethylamino)ethylene (TDAE) at 440 or 390 nm provides a quantitative reductant capable of reducing aryl chlorides and fluorides. The photoactive excited state lifetime of TDAE in cyclohexane is 17.3 ns at room temperature, with an oxidation potential of about -3.4 V for SCE.

2-Chloro-4-fluorobenzonitrile may be used in the preparation of 2-chloro-3,4-diaminobenzonitrile.
