    摘要: A bis-phosphonium salt represented by the following formula (1) is provided: wherein R1, R2, R3, and R4 each represent a linear or branched alkyl group, a cycloalkyl group, an aryl group, or an aralkyl group; A represents an alkylene group; Y represents an anion; R1 and R2 may form a ring; R3 and R4 may form a ring; and R1, R2, R3, and R4 may be the same or different. A process for producing such a bis-phosphonium salt includes a step of allowing a first secondary phosphine and second secondary phosphine to react with a compound in an alcohol solvent selected from a secondary alcohol and tertiary alcohol. The compound is represented by the following formula (5): Y—A—Y  (5)

    摘要: The present invention provides a method of preparing a phosphonium salt of the formula [R1R2R3P—CR4R5R6]X, comprising ball-milling a phosphine of the formula R1R2R3P with a compound of the formula XCR4R5R6; a method of preparing a phosphorus ylide of the formula R1R2R3P═CR4R5, comprising ball-milling a phosphonium salt of the formula [R1R2R3P—HCR4R5]X in the presence of a base; and a method of preparing an olefin of the formula R4R5C═CR7H or R4R5C═CR7R8, comprising ball-milling a phosphorus ylide of the formula R1R2R3P═CR4R5 with a compound of the formula R7C(O)H or R7C(O)R8. The inventive method produces phosphonium salts and phosphorus ylides by mechanical processing solid reagents under solvent-free conditions. The advantages of the present invention over conventional solution methods, include: (1) extremely high selectivity; (2) high yields; (3) low processing temperatures; (4) simple and scalable reactions using commercially available equipment; and (5) the complete elimination of solvents from the reaction.

    摘要: A process for preparing phosphonium phenolate is disclosed. The process entails a reaction of phosphonium halide with phenol in an aqueous alkaline solution at a temperature of 0 to 55° C. The molar ratio of phenol to phosphonium halide is between 2:1 to 10:1 and the pH of the solution is 9.5 to 11. An optional embodiment entails carrying out the reaction in the further presence of alcohol.

    摘要: The invention relates to a process for the purification of phosphonium salts in which a solution of the crude phosphonium salt is passed over a bed of a cation exchange resin in salt form or of an adsorber resin, the resin is washed with a polar protic solvent in the case of the cation exchange resin and with an electrolyte solution and a nonpolar solvent in the case of the adsorber resin, and the phosphonium salt is eluted from the cation exchange resin with an electrolyte solution or from the adsorber resin with a polar solvent.
