摘要

Substituted N-phenylglutarimides (I), wherein X<1>, X<2> = O, S; R<1> = halogen, NO2, CN, CF3; R<2> = H, halogen; R<3>, R<4>, R<5> = H, halogen, CN, alkyl, cycloalkyl, alkenyl, alkinyl, alkyl halide, alkoxy, alkoxy halide, alkyl thio, alkyl thio halide, cyanoalkyl, alkoxy carbonyl, possibly substituted phenyl or benzyl, or 2 substituents of a C atom of the glutarimide ring are linked via a possibly substituted chain, or 2 substituents of adjacent C atoms of the glutarimide ring are linked via a possibly substituted chain; A = CHR<6>-CHR<7>-CO-B or CR<6>=CR<8>-CO-B; R<6> = H, C1-C6-alkyl or C1-C6-alkyl halide; R<7> = halogen, alkyl halide, OH, alkoxy or alkyl carbonyl alkoxy; R<8> = H, halogen, CN, alkyl, alkyl halide, OH, alkoxy, alkyl carbonyl, alkoxy carbonyl or alkyl carbonyloxy; B = H, alkyl, alkenyl, alkinyl, alkyl halide, cycloalkyl, alkoxy alkyl, dialkoxy alkyl, alkyl thioalkyl, OR<9>, SR<9>, NR<10>, R<11>; R<9> = H, alkyl, alkenyl, alkinyl, cycloalkyl, alkyl halide, cyanoalkyl, alkenyl halide, alkoxy carbonyl alkyl, alkoxyalkyl, alkyl thioalkyl, alkylimino, alkylimino alkyl, possibly substituted phenyl or benzyl; R<10>, R<11> = H, alkyl, alkenyl, alkinyl, cycloalkyl, alkyl halide, alkyl carbonyl, alkoxy carbonyl, alkoxy alkyl, possibly substituted phenyl, or R<10> und R<11> together with the common N atom = saturated or unsaturated 4- to 7- membered heterocycle with 1-2 other heteroatoms, as well as salts of (I) that are tolerable to plants; their preparation and use as herbicides and desiccants/defoliants, as well as preproducts for preparing the N-phenylglutarimides (I).
