- W2000434148 abstract "This paper reports the synthesis and insecticidal activities of benzoyl arylureas in which the aryl group bears a polyfluoroalkoxy or (polyfluoroalkoxy)alkoxy side-chain. The activity of these compounds has been evaluated against larvae of S. littoralis, A. aegypti and L. decemlineata.The effects have been studied of varying (a) the substituents, R1 and R2 in the 2-and 6-positions of the benzoyl moiety; (b) the polyfluoroalkoxy chain R1 in the 4-position of the aryl moiety; and (c) the other substituent(s), R3, on this ring.In general, the highest activities were achieved against S. littoralis when R1, R2 = F, R3 = 2-F and R1 = OCF2CFHOCF3 or R1 = Cl and R2 = H. R3 = 2-Cl and R1 = OCF2CFHOCF3; against A. aegypti when R1, R2 = F. R3 = 3-F and R1 = OCF2CFHOCF3 or R1 = Cl and R2 = H. R3 = 3-F and R1 = OCF2CFHOCF3; and against L. decemlineata by compounds in which R1 = Cl and R2 = H. R3 = 3. 5-CI and R1 = OCF2CFHOCF3, R1, R2 = F, R3 = 3.5-Cl and R1 = OCF2CFHOCF2CF3, R1, R2 = F, R3 = 3-CI and R1 = OCF2CFHOCF2CF2CF3. The greatest overall insecticidal activities were achieved when R1, R2 = F, R3 = 2-F and R1 = OCF2CFHOCF3 and when R1, R2 = F, R3 = 3-Cl and R1 = OCF2CFHOCF3." @default.
