The chlorination reaction of O-alkyl S-alkyl(aryl) thiophosphoric(-nic) acid derivatives with phosphorus oxychloride

It is reported that a variety of O-alkyl S-alkyl(aryl) thiophosphoric(-nic) acid derivatives 4 can be readily chlorinated with phosphorus oxychloride giving S-alkyl(aryl) thiophosphoro(-no)chloridates 2 and O-alkyl phosphorodichloridates 3.

Production of phosphoro chloride thiolates

A process for the production of a phosphoro chloride thiolate of the formula STR1 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 and an alkyl dichloro-phosphite of the formula with a sulphenyl chloride of the formula to produce a mixture of a phosphorochloridothiolate of the formula STR2 and a phosphorodichloridothiolate of the formula STR3 and reacting the mixture without isolation with an alcohol of the formula in the presence of a dehydrochlorinating agent thereby to convert the phosphorodichloridothiolate of the formula STR4 to additional phosphorochloridothiolate STR5 The starting mixture is produced by reacting phosphorus trichloride with a trialkyl phosphite, or with an alcohol in the presence of a dehydrochlorinating agent.
