    摘要： Compositions of stabilized forms of organometallic reagents, methods of preparing the stabilized forms, and methods of using the stabilized forms, are provided. Stabilized organometallic reagent compositions of the invention are sorbent solids permeated by the organometallic reagent. The reagent can be a Grignard reagent, a Reformatsky reagent, a zinc reagent of the type RZnX, R2Zn, Ar2Zn, R3ZnM, Ar3ZnM, and the like, an organolithium reagent such as n-butyllithium, a organocopper reagent, or other reactive, potentially pyrophoric reagent. The compositions are solids that can be weighed and dispensed in ambient air without requiring inert gas blanketing. The compositions can be prepared by contacting the sorbent solid, which can be silica, an alkyl silica, alumina, or other non-reactive sorbent solid with a solution of the organometallic reagent in a non-reactive solvent, then, removing the solvent, such as under vacuum. The stabilized composition can be used by extracting the organometallic reagent from the composition with a non-reactive solvent and contacting the solution with a reactant.

    摘要： 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.
