A process for preparing a S-substituted phosphorochloridothiolate having the formula: ##STR1## wherein R.sup.1 is a chlorine atom or an alkoxy or phenoxy group which may be substituted, and R.sup.2 is an alkyl, alkenyl, alkynyl, cycloalkyl or phenyl group which may be substituted, which comprises isomerizing an O-substituted phosphorochloridothionate having the formula: ##STR2## wherein R.sup.1 and R.sup.2 are as defined above, in the presence of a Lewis acid catalyst or a phosphorus compound catalyst.
一种制备具有以下式子的S-取代磷酸氯硫酯的方法:##STR1## 其中R1是氯原子或可能被取代的烷氧基或苯氧基,R2是可能被取代的烷基、烯基、炔基、环烷基或苯基。该方法包括在路易斯酸催化剂或磷化合物催化剂的存在下,使具有以下式子的O-取代磷酸氯硫酸盐异构化:##STR2## 其中R1和R2如上所定义。
