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.
提供了一种新型的1-氟-1,1-双(芳基磺酰基)甲烷,可用于单氟甲基化。同时提供了其生产方法。一种制备氟双(芳基磺酰基)甲烷的方法,包括以下步骤:用碱处理下式(1)所表示的双(芳基磺酰基)甲烷,(ArSO2)2CH2 (1)(其中Ar表示取代或未取代的苯基或萘基);然后加入氟化试剂,以产生下式(2)所表示的氟双(芳基磺酰基)甲烷,(ArSO2)2CHF (2)(其中Ar的定义如上),以及上述式(2)所表示的氟双(芳基磺酰基)甲烷(2),是一种非常有用的新化合物,可用于制备单氟甲基。
