摘要 |
HERBICIDAL ARYLOXY PHENOXY ACYL MALONATES A b s t r a c t The invention relates to new aryloxy phenoxy acyl malonates of the general Formula I (I) a process for the preparation thereof and herbicidal compositions comprising the same. In the general Formula I R1 stands for halogen, trifluoromethyl, trifluoromethoxy, cyano, or hydrogen; R2 represents hydrogen, halogen or methyl; R3 is C1-4 alkyl; and the R3 substituents may be the same or different, X stands for -N= or -CH= and n is 0 or 1. The compounds of the general Formula I may be prepared by reacting a compound of the general Formula II (II) with a metal derivative of a malonate of the general Formula III 3 (III) or in the presence of a metal compound with a malonate of the general Formula III; or reacting a compound of the general Formula IV (IV) with a compound of the general Formula V; (V) or reacting a compound of the general Formula VI (VI) with a compound of the general Formula VII VII (in which Formulae R1, R2, R3, X and n are as stated above; Y stands for halogen, cyano or alkylcarbonyloxy; Z represents halogen; and if Q is hydroxy or alkali metal oxy, P stands for halogen, or if Q stands for halogen P represents hydroxy or alkali metal oxy). The new compounds of the general Formula I possess valuable herbicidal properties. |
