PROCESS FOR THE PREPARATION OF PHOSPHORCHLORIDE THIOLATES |
| 摘要 |
A process for the production of a phosphoro chloride thiolate of the formula <IMAGE> wherein R1 is alkyl, alkoxyalkyl, aryl, or aryl substituted by alkyl, alkoxy or halogen, and R2 is alkyl, comprising reacting a mixture of a dialkyl chlorophosphite of the formula (R2O)2PCl and an alkyl dichloro-phosphite of the formula (R2O)PCl2 with a sulphenyl chloride of the formula R1SCl to produce a mixture of a phosphorochloridothiolate of the formula <IMAGE> and a phosphorodichloridothiolate of the formula <IMAGE> and reacting the mixture without isolation with an alcohol of the formula R2OH in the presence of a dehydrochlorinating agent thereby to convert the phosphorodichloridothiolate of the formula <IMAGE> to additional phosphorochloridothiolate <IMAGE> The starting mixture is produced by reacting phosphorus trichloride with a trialkyl phosphite, or with an alcohol in the presence of a dehydrochlorinating agent. |
