Zusammenfassung:PROCESS FOR THE PREPARATION OF THE O,O-DIMETHYL-O-(2,2-DICHLOROVINYL) ESTER OR THE O,O-DIETHYL-O-(2,2-DICHLORO- A b s t r a c t The present invetion relates to an unobvious process for the preparation of the 0,0-dimethyl-0-(2,2-di-chlorovinyl) ester or the 0,0-diethyl-0-(2,2-dichloro-vinyl) ester of thionophosphoric acid, which esters are known as insecticides. It has already been disclosed in the literature that the 0,0-dimethyl-0-(2,2-dichlorovinyl) ester of thionophosphoric acid can be obtained when the 0-(2,2-di-chlorovinyl) ester of thionophosphoric acid dichloride is reacted with methanol.
