More Information
Summary:NEW MATERIAL:A compound of formula I [X is halogen, alkyl, alkoxy, NO2; n is 1-4; A is halogen, alkyl, alkoxy, H; B is CX1 (X1 is H, halogen), N; R , R are H, alkyl; E is H, halogen, OH; Q is formula II - formula V (Y is halogen, alkyl, alkoxy, CN; m is 1-5)]. EXAMPLE:4-Chloro-5-(4-chlorobenzyloxy)-2-(4-chlorophenyl)-3(2H)-pyrida zinone. USE:Insecticide. It has very strong specificity against certain kinds of insect pests such as Hemiptera, Coleoptera and sanitarily harmful insects. Additionally, it exerts high residual effect. PREPARATION:The reaction of a compound of formula VI (X' is halogen, OM; M is H, alkali metal) with another compound of formula VII (X'' is OM, when X' is halogen, vice versa) gives the compound of formula I.
