피리딘,2-[(디플루오로메틸)술포닐]- 화학적 특성, 용도, 생산

• 개요

  Difluoromethyl 2-pyridyl sulfone, also known as Hu reagent, is a novel and efficient gem-difluoroolefination reagent for preparing gem-difluoroalkenes from both aldehydes and ketones. The fluorinated sulfinate intermediates during the gem-difluoroolefination is relatively stable, and can be halogenated in situ to afford bromo- and iododifluoromethyl compounds. It can also act as nucleophilic difluoro(sulfonato)methylation reagent for the synthesis of α,α-difluorosulfonates from aldehydes, and alkyl halides and triflates.

• 화학적 성질

  Melting point 48-50°C, boiling point 324.4+42°C, relative density 1.423+0.06 g/cm³ , slightly soluble in water, casily soluble in acctonitrile and methanol.

• 용도
