(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)
(ArSO

CHF (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。还提供了一种其生产方法。一种制备氟双(芳基磺酰基)甲烷的方法,包括以下步骤:用碱处理以下式子(1)所表示的双(芳基磺酰基)甲烷(ArSO2)2CH2(1)(其中Ar代表取代或未取代的苯基或萘基),然后加入氟化试剂,制备以下式子(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),以及上述式子(2)所表示的新型化合物氟双(芳基磺酰基)甲烷(2),在单氟甲基化生产中非常有用。
