N-Substd. methyl N-acyloxy:acetyl-aniline derivs. - useful as systemic fungicides, esp. for control of Oomycetes

摘要

Anilides of formula (I) are new. In (I) R1 is 1-4C alkyl or alkoxy, or halo; R2 and R3 are H, 1-3C alkyl or halo; R2 can also be 1-4C alkoxy; R4 is H or CH3 and the total no- of C in R1, R2, R3 and R4 =8. X is CH2 or CHCH3; R5 is COQCH3, COQC2H5 or CH2OCH3; Q iS S or O; R6 is H or CH3; R7 is 1-4C alkyl (opt. substd. by halo, CN, SCN, 1-4C alkoxy or alkylthio). 2-5C alkenyl or 3-7C cycloalkyl (opt. substd. by >=1 halo), phenyl or benzyl (opt. substd. by halo, NO2, 1-4C alkyl or alkoxy), or 5-6 membered heterocycle opt. substd. by CH3). They are prepd. e.g. by acylating appropriate anilines with Hal.COCH2R6OCOR7. (I) are systemic fungicides partic. effective against Oomycetes such as Phytophthora, Peronospora, Pseudoperonospora, Pythium or Plasmopara. They can be applied to plants, seeds etc. in standard formulations.
