  • Patent number: 7638654
    Abstract: A novel 1-fluoro-1,1-bis(arylsulfonyl)methane is provided which is useful in monofluoromethylation. Also provided is a production method thereof. A method for producing a fluorobis(arylsulfonyl)methane, the method including the steps of: treating a bis(arylsulfonyl)methane represented by the following formula (1), (ArSO2)2CH2??(1) (wherein Ar represents a substituted or unsubstituted phenyl group or naphthyl group) with a base; and then adding a fluorination reagent thereto, to produce fluorobis(arylsulfonyl)methane represented by the following formula (2) (ArSO2)2CHF??(2) (wherein Ar is defined as above), and a fluorobis(arylsulfonyl)methane (2) represented by the above formula (2), which is a novel compound that is very useful in producing a monofluoromethyl.
