摘要：
A process for preparing a S-substituted phosphorochloridothiolate having the formula:
wherein R 1 is a chlorine atom or an alkoxy or phenoxy group which may be substituted, and R 2 is an alkyl, alkenyl, alkynyl, cycloalkyl or phenyl group which may be substituted, which comprises isomerizing an O-substituted phosphorochloridothionate having the formula:
wherein R 1 and R 2 are as defined above, in the presence of a Lewis acid catalyst or a phosphorus compound catalyst.
