    摘要: Polymerizable fluorinated ester compounds having formulae (1) and (2) are novel wherein R1 is H, methyl or trifluoromethyl, R2 and R3 are H or a monovalent hydrocarbon group, R2 and R3 may form a ring, R4 is H, OH or a monovalent hydrocarbon group, and R5 is an acid labile group. They are useful as monomers to produce polymers for the manufacture of radiation-sensitive resist compositions which have high transparency to radiation having a wavelength of up to 500 nm and exhibit good development properties due to the presence of phenol-like acidic hydroxyl groups.

    摘要: The present invention provides a method capable of simply producing optically active halopropanediol derivatives useful as pharmaceutical intermediates from inexpensive raw materials. Monohalohydroxyacetone derivatives can be produced by reacting propargyl alcohol derivatives available at low cost and a hypohalogenous acid to convert the propargyl alcohol derivatives to di- or tri-halohydroxyacetone derivatives, and then hydrogenating the derivatives in the present of a transition metal catalyst. Also, optically active halopropanediol derivatives can be produced by stereoselectively reducing the halohydroxyacetone derivatives with an enzyme source having the ability to stereoselectively reduce the carbonyl groups of the halohydroxyacetone derivatives.

    摘要: Oligomers of tetrafluoroethylene (C2F4)n where n is 4 to 6 react at 25*-100*C with aqueous solutions of sodium or potassium hydroxides to give novel oxygen-containing derivatives in which the oxygen is located in hydroxyl, carbonyl or carboxyl groups. With 5-15% by weight solutions of the hydroxides the tetramer yields a tertiary alcohol; the pentamer yields the ketone (C2F5)2(CF3)C.CH2COCF3, and hexamer yields a mixture of the ketone (C4F9)(C2F5)(CF3)C.CH2COCF3 and the ketene (C2F5)2(CF3)C.C(CO).CF(CF3)(C2F5). With 30-60% solutions the pentamer yields the acid (C2F5)2(CF3)C.CH2COOH. These oligomer derivatives are intermediates for making surfactants and oleophobic compounds for application to textiles and leather.
