The photoinduced reductive dehalogenation promiscuity of cyclohexanone monooxygenase (CHMO) with a novel mechanism of ET/PT distinct from the photoinduced promiscuity of natural reductases is reported. Various highly enantioenriched α-fluoroketones were synthesized by photoinduced reductive dehalogenation of α,α-halofluoroketones in a process catalyzed by the rationally designed CHMO mutants.
