    Abstract: Disclosed are methods of producing fluorinated alcohols which find particular use in the syntheses of pharmaceutical drugs. The methods comprise generally, the steps of (a) reacting a halogenated alkane with an alkyl vinyl ether to form an unsaturated halogenated aldehyde; (b) reducing the unsaturated halogenated aldehyde to form an unsaturated halogenated alcohol; and (c) reducing the unsaturated halogenated alcohol to form a fluorinated alcohol.
