    摘要： The invention relates to a method for producing 3,3-dichloro-1,1,1-trifluoroacetone. This method includes a step of fluorinating pentachloroacetone by hydrogen fluoride in the presence of a fluorination catalyst. This fluorination may be conducted in a liquid phase in the presence of an antimony compound as the fluorination catalyst. Alternatively, the fluorination may be conducted in a gas phase in the presence of a fluorination catalyst which may be a fluorinated alumina or at least one compound of at least one metal selected from Al, Cr, Mn, Ni, and Co. The method is suited to an industrial scale production of 3,3-dichloro-1,1,1-trifluoroacetone. The invention further relates to another method for producing 3,3-dichloro-1,1,1-trifluoroacetone. This method includes a step of purifying a crude 3,3-dichloro-1,1,1-trifluoroacetone by a distillation in the presence of water, thereby to produce 3,3-dichloro-1,1,1-trifluoroacetone which is substantially free of organic matters other than 3,3-dichloro-1,1,1-trifluoroacetone. This crude 3,3-dichloro-1,1,1-trifluoroacetone may be the reaction products of the fluorination of pentachloroacetone in a gas phase. Due to the provision of the another method, 3,3-dichloro-1,1,1-trifluoroacetone can be produced with high yield.

    摘要： The invention relates to a method for producing a first perhalogenated cyclopentene represented by the general formula: C5ClBF8−B where B is an integer of from 0 to 7. The method includes a step of (a) fluorinating a second perhalogenated cyclopentene by hydrogen fluoride in a gas phase in the presence of a fluorination catalyst. The second perhalogenated cyclopentene is represented by general formula: C5ClAF8−A where A is an integer of from 1 to 8, and A is not smaller than B. With this method, the first perhalogenated cyclopentene (e.g., 1,2-dichloro-3,3,4,4,5,5-hexafluorocyclopentene, another chlorofluorinated cyclopentene, or octafluorocyclopentene) can continuously easily be produced, for example, from octachlorocyclopentene obtained by chlorination of hexachlorocyclopentadiene that is easily available. Therefore, the above method is very useful as an industrial scale production method. In case that the first perhalogenated cyclopentene is octafluorocyclopentene, the method may further include a step of (b) fluorinating a reaction product of the step (a) in a way that is different from that of the step (a), thereby to convert said reaction product of the step (a) into octafluoropentene. The step (a) may be conducted by a multistep reaction wherein there are provided “m” of reaction zones in number where m is an integer of from 2 to 10. In this case, the reaction zones are arranged in series and such that a reaction temperature of each reaction zone is independently controllable.

    摘要： 1-β-D-Arabinofuranosyluracil in 3′,5′-hydroxyl-protected form is reacted with a trifluoromethanesulfonylating agent in the presence of an organic base to convert it into a 2′-triflate form, and then it is reacted with a fluorinating agent containing “a salt or complex formed by an organic base and hydrofluoric acid” to produce 2′-deoxy-2′-fluorouridine in 3′,5′-hydroxyl-protected form. A deprotecting agent is further caused to act thereon to obtain 2′-deoxy-2′-fluorouridine. The 2′-deoxy-2′-fluorouridine obtained can efficiently be purified by temporarily converting it into a 3′,5′-diacetyl form, recrystallizing the 3′,5′-diacetyl form, and then deacetylating it. Thus, high-purity 2′-deoxy-2′-fluorouridine can be produced.
