Difluoromethyl 2-pyridyl sulfone C화학적 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.용도
