New 2 - (1 - (3 - chlorine allyloxy amino) alkylidene) - 5 - alkyl thio alkyl cyclo hexane - 1,3 - of dihydroxydiones, to processes for their preparation and herbicidal agents containing them

摘要

2-[1-(3-chloroallyloxyamino)propylidene]-5-(substituted)-cyclohexane-1 ,3-dione derivatives, namely 2-[-1(3-chloroallyloxyamino)propylidene[-5-2(2-methylthiopropyl)-cyclo hexane-1,3-dione and 2-[1-(3-chloroallyloxyamino)propylidene]-5-(2-propylthioethyl)-cyclohe xane-1,3-dione, unexpectedly exhibit any markedly superior herbicidal activity compared with close analogues thereof.
