Preparation of 1,1-difluoroalkanes from aldehydes via 1,1-bistriflates: Advantageous use of HF-Lewis base reagents

Alkane-1,1-bistriflates, prepared in excellent yields by reaction of aldehydes with triflic anhydride, are converted to their respective 1,1-difluoroalkanes in good to excellent yield through reaction with fluorinating agent, triethylaminetrishydrofluorid

FLUORIERUNGSEIGENSCHAFTEN VON WF6

WF6 reacts with aliphatic carbonyl- or carboxyl derivates to form the corresponding difluorides or carbonic acid fluorides.Fluorination of carbonyl compounds makes the presence of a Lewis acid like BF3 necessary.Trifluoromethyl compounds are not available in this way.Selective fluorination of alcoholes with WF6 is not possible.
