피리딘,2-[(디플루오로메틸)술포닐]- 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.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
2-[(Difluoromethyl)sulfonyl]pyridine is a new novel gem-difluoroolefination reagent for both aldehydes and ketones.일반 설명
Difluoromethyl 2-pyridyl sulfone (2-PySO2CF2H) is a reagent used in the gem-difluoroolefination of aldehydes and ketones. It is also used as a reagent in the nucleophilic difluoro(sulfonato)methylation of alcohols, N-sulfinyl imines, and halides.피리딘,2-[(디플루오로메틸)술포닐]- 준비 용품 및 원자재
