  • Publication number: 20130303774
    Abstract: A production method of a ?-fluoroalcohol includes performing a reaction of an ?-fluoroester with hydrogen gas (H2) in the presence of a specific ruthenium complex (i.e. a ruthenium complex of the general formula [2], preferably a ruthenium complex of the general formula [4]). This production method can employ a suitable hydrogen pressure of 1 MPa or less by the use of such a specific ruthenium complex and does not require a high-pressure gas production facility when put in industrial practice. In addition, this production method can remarkably reduce the amount of catalyst used therein (to e.g. a substrate/catalyst ratio of 20,000) in comparison to the substrate/catalyst ratio conventional reduction of ?-fluoroalcohol. It is possible by these reduction in hydrogen pressure and catalyst amount to largely reduce the production cost of the ?-fluoroalcohol.

  • Patent number: 7795478
    Abstract: A fluorine-containing benzaldehyde is reacted with an alkyl Grignard reagent to convert it to a magnesium alkoxide of racemic, fluorine-containing, benzyl alcohol, and subsequently the magnesium alkoxide is reacted with phthalic anhydride to obtain a phthalate half ester of racemic, fluorine-containing, benzyl alcohol, and the half ester is optically resolved by optically active 1-phenylethylamine, and then the ester group is hydrolyzed, thereby producing an optically active, fluorine-containing, benzyl alcohol.
