Claims
- 1. A method for non-catalytically producing a tertiary phosphine dichloride comprising directly reacting chlorine and carbon monoxide with a tertiary phosphine oxide of the formula (I): ##STR3## wherein R, R.sup.1 and R.sup.2 respectively represent, independently from each other, a substituted or unsubstituted alkyl group having 1 through 18 carbon atoms, a substituted or unsubstituted cycloalkyl group having 5 to 10 carbon atoms or a substituted or unsubstituted aryl group having 6 through 14 carbon atoms; and wherein, when substituted, one or more of said groups R, R.sup.1 and R.sup.2 have at least one substituent selected from the group consisting of chlorine and fluorine atoms, a cyano group and alkoxy groups having 1 through 6 carbon atoms.
- 2.

- 3. A method as claimed in claim 1, wherein the carbon monoxide in the reaction mixture has a pressure of from 1 to 100 atmospheres.
- 4. A method as claimed in claim 1, wherein said reaction is carried out in a halogenated hydrocarbon solvent which is not reactive to the reaction mixture.
- 5. A method as claimed in claim 1, wherein said solvent is selected from the group consisting of tetrachloromethane, fluorotrichloromethane, 1,1,2-trichloro-1,2,2-trifluoroethane and 1,1,2,2-tetrachloroethane.
- 6. A method as claimed in claim 1, wherein said reaction is carried out at a temperature of from -20.degree. to 100.degree. C.
- 7. A method for non-catalytically producing a tertiary phosphine dichloride comprising directly reacting chlorine and carbon monoxide with a tertiary phosphine oxide of the formula (I): ##STR4## wherein R, R.sup.1 and R.sup.2 respectively represent, independently from each other, a substituted or unsubstituted alkyl group having 1 through 18 carbon atoms, or a substituted or unsubstituted cycloalkyl group having 5 to 10 carbon atoms, and wherein, when substituted, one or more of said groups R, R.sup.1 and R.sup.2 have at least one substituent selected from the group consisting of chlorine and fluorine atoms, a cyano group and alkoxyl groups having 1 through 6 carbon atoms.
- 8. A method as recited in claim 7 wherein said tertiary phosphine oxide is selected from the group consisting of trimethylphosphine oxide, triethylphosphine oxide, tripropylphosphine oxide, tributylphosphine oxide, trioctylphosphine oxide, tricyclohexylphosphine oxide, tris (2-cyanoethyl) phosphine oxide, dimethylchloromethylphosphine oxide, methylethylbutylphosphine oxide, tris (trifluoromethyl) phosphine oxide and tris (2-fluoroethyl) phosphine oxide.
- 9. A method as claimed in claim 7, wherein the carbon monoxide in the reaction mixture has a pressure of from 1 to 100 atmospheres.
- 10. A method as claimed in claim 7, wherein said reaction is carried out in a halogenated hydrocarbon solvent which is not reactive to the reaction mixture.
- 11. A method as claimed in claim 7, wherein said solvent is selected from the group consisting of tetrachloromethane, fluorotrichloromethane, 1,1,2-trichloro-1,2,2-trifluoroethane and 1,1,2,2-tetrachloroethane.
- 12. A method as claimed in claim 7, wherein said reaction is carried out at a temperature of from -20.degree. to 100.degree. C.
