Abstract
An asymmetric phosphinoselenoic chloride of the present invention is represented by the general formula: 1 wherein Ar represents an aryl group and R represents an aryl group, an alkyl group having 3 or more carbon atoms, or an alkoxy group. The asymmetric phosphinoselenoic chloride is a novel compound and is useful as synthetic raw materials, agricultural chemicals, pharmaceutical products and the like.
Claims10
An asymmetric phosphinoselenoic chloride represented by the general formula:
- 13
- wherein Ar represents an aryl group and R represents an aryl group, an alkyl group having 3 or more carbon atoms, or an alkoxy group.
A method for producing an asymmetric phosphinoselenoic chloride, the method comprising:
- mixing arylphosphine dichloride, an organometallic reagent, and selenium in a solvent so as to cause a reaction of the arylphosphine dichloride, the organometallic reagent, and the selenium,
- wherein the arylphosphine dichloride is represented by the general formula (1):
- ArPCl2 (1)
- wherein Ar represents an aryl group;
- and
- the organometallic reagent is represented by the general formula (2) or (3):
- R—M (2)
- wherein R represents an aryl group, an alkyl group having 3 or more carbon atoms, or an alkoxy group;
- and M represents lithium or sodium,
- R—NX (3)
- wherein R represents an aryl group, an alkyl group having 3 or more carbon atoms, or an alkoxy group;
- N represents magnesium, copper, or zinc;
- and X represents halogen.
