    • A process for the production of a phosphoro chloride thiolate of the formula ##STR1## wherein R.sup.1 is alkyl, alkoxyalkyl, aryl, or aryl substituted by alkyl, alkoxy or halogen, andR.sup.2 is alkyl,comprising reacting a mixture of a dialkyl chlorophosphite of the formula(R.sup.2 O).sub.2 PCland an alkyl dichloro-phosphite of the formula(R.sup.2 O)PCl.sub.2with a sulphenyl chloride of the formulaR.sup.1 SClto 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 formulaR.sup.2 OHin 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.
    • 制备式IMAMA的磷酰氯硫醇盐的方法,其中R 1是被烷基,烷氧基或卤素取代的烷基,烷氧基烷基,芳基或芳基,R 2是烷基,包括使二氯甲基亚磷酸二 式(R 2 O)2 PCl和式(R 2 O)PCl 2的烷基二氯 - 亚磷酸酯与式R 1 SCl的磺酰氯反应,生成下式的下式的次氯酸硫代硫酸酯与式“IMAGE”的二氯代硫代磷酸酯的混合物, 该混合物在脱氯化氢剂的存在下不用式R 2 OH的醇分离,从而将式“IMAGE”的二氯二硫代磷酸酯转化为另外的氯代硫代磷酸酯。起始混合物通过使三氯化磷与三烷基亚磷酸酯反应制备,或 在脱氯化氢剂存在下用醇。
