Zusammenfassung:NEW MATERIAL:A compound of formula I (X is H or halogen; X is halogen; Y is OH, alkoxyl, alkylaminocarboxy, alkoxycarbonylmethoxyl, etc.; Z is substituted phenyl or substituted pyridyl). EXAMPLE:N-( 4-Chlorophenylcarbamoyl )- O-( O',O'- dimethylphosphorothiono)-2,6- difluorobenzamidoxime. USE:An insecticide capable of exhibiting the activity as an active constituent in the insecticidal agent, and effective against injurious insects belonging to Plutella xylostella, carbage armyworm, housefly, common gnat, etc. PROCESS:A compound of formula II (either one of X and X is amino, and the other is isocyanate) is reacted with a compound of formula III to give the aimed compound of formula I . The reaction is usually carried out preferably at 0- 150 deg.C in the presence of a solvent, e.g. tetrahydrofuran (THF) or diethyl ether.
