HYDROXY QUINOLINE CARBAMATES, AND THEIR USE AS INSECTICIDES

摘要

Hydroxy quinoline carbamates of the general formula wherein one of the radicals R1 and R3 represents a group of formula II and the other represents hydrogen, (C1 - C6) alkyl, or (C1 - C4) alkoxy carbonyl; R2 represents hydrogen, (C1 - C6) alkyl, (C1 - C3) alkyl-carbonyl, (C1 - C6) alkoxy carbonyl, or nitro, or R1 and R2 taken together represent a tetramethylene group; R4 represents a tetramethylene group or a radical -CH=CH-CH=CH-completing the tetrahydroquinoline or quinoline nucleus, respectively, and which may optionally be substituted by halogen. (C1 - C18) alkyl, (C1 - C3) alkoxy, (C1 - C3) alkylthio, halogen (C1 - C2) alkoxy, trifluoromethyl, (C5-C7)cycloalkyl, phenoxy, -NH2, di-(C1 - C4) alkylamino, -NO2, (C1 - C3) alkyl carbonyl, or (C1 - C6) alkoxy carbonyl; or R4 represents a radical chosen from:-CH=CH-N=CH-; ; ; ; O R R5 and R6 represent CH3 or C2H5, and X represents oxygen or sulphur, are valuable insecticides and particularly aphicides.
