Abstract: Disclosed are a water-repellent protective film forming agent for forming a water-repellent protective film on a silicon element-containing surface of a wafer and a water-repellent protective film forming liquid chemical in which the water-repellent protective film forming agent is dissolved in an organic solvent, characterized in that the water-repellent protective film forming agent consists of at least one kind of silicon compound selected from the group consisting of a sulfonimide derivative represented by the following general formula [1], a sulfonimide derivative represented by the following general formula [2] and a sulfonmethide derivative represented by the following general formula [3].

Abstract: A novel means for accelerating the flowering time in Rosaceae fruit trees such as apples and pears is provided, by inoculating a viral RNA into a cotyledon of a Rosaceae fruit tree seedling immediately after rooting with a particle gun technique, wherein the viral RNA is concentrated from a proliferating host infected with a recombinant apple latent spherical virus (FT-ALSV) expressing an Arabidopsis FT gene.

Abstract: There is provided a method for producing a tris(perfluoroalkanesulfonyl)methide acid salt represented by formula [1], including the steps of (a) reacting a methylmagnesium halide represented by formula [2] with a perfluoroalkanesulfonyl fluoride represented by formula [3], thereby obtaining a reaction mixture; and (b) directly reacting the obtained reaction mixture with at least one selected from the group consisting of alkali metal halides, quaternary ammonium salts, and quaternary phosphonium salts. By this method, it is possible to easily produce the target methide acid salt with high yield.
