摘要

NEW MATERIAL:A compound expressed by formula I (X is H or Cl; R is hexafluoroisopropyl or heptafluoroethyl; R1 is H, acetyl, propionyl, me thoxyacetyl, etc.). EXAMPLE:N-[2,2,2-Trichloro-1-(2,2,3,3,4,4,4-heptafluorobutoxy)-ethyl]- 0-acetylsali cylamide. USE:An agricultural and horticultural germicide and herbicide, useful for downy mildew of cucumber, late blight of tomato, gray mold of kidney bean, etc., and capable of exhibiting a wide range of antimicrobial spectrum against various plant pathogenic germs and showing improved herbicidal activity against weeds in paddy field as well as upland field. PREPARATION:An N-(1,2,2,2-tetrachloroethyl)-0-acetyl-substituted salicylamide derivative expressed by formula II (R1 is COCH3), is reacted with a fluorinated alcohol in the presence of triethylamine in a solvent, e.g. benzene, etc., to afford the aimed compound expressed by formula I.
