DESCRIPTION:
BRIEF SUMMARY
This application is a 371 of PCT/EP96/00007 filed Jan. 4, 1996.
The present invention relates to novel substituted 2-phenylpyridines of the formula I ##STR2## where the variables have the following meanings: n is 0 or 1; halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -haloalkyl, hydroxyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy, nitro, amino, C.sub.1 -C.sub.4 -alkylamino, di-(C.sub.1 -C.sub.4 -alkyl)-amino, mercapto, C.sub.1 -C.sub.4 -alkylthio, C.sub.1 -C.sub.4 -haloalkylthio, cyano, carboxyl, (C.sub.1 -C.sub.4 -alkoxy)carbonyl, aminocarbonyl, C.sub.1 -C.sub.4 -alkylaminocarbonyl or di-(C.sub.1 -C.sub.4 -alkyl)-aminocarbonyl; -haloalkyl, cyano, nitro, amino, hydroxyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy, mercapto, C.sub.1 -C.sub.4 -alkylthio, C.sub.1 -C.sub.4 -haloalkylthio, C.sub.1 -C.sub.4 -alkylsulfinyl, C.sub.1 -C.sub.4 -haloalkylsulfinyl, C.sub.1 -C.sub.4 -alkylsulfonyl or C.sub.1 -C.sub.4 -haloalkylsulfonyl; halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -alkoxy or C.sub.1 -C.sub.4 -haloalkoxy; --CH.sub.2 --CH(R.sup.11)--CO-- or --CH.dbd.C(R.sup.11)--CO--, where R.sup.9 and R.sup.10 independently of one another are hydrogen or C.sub.1 -C.sub.4 -alkyl and R.sup.11 is hydrogen, halogen or C.sub.1 -C.sub.4 -alkyl; ##STR3## R.sup.12 is hydrogen, hydroxyl, halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, (C.sub.1 -C.sub.4 -alkyl)carbonyloxy, (C.sub.1 -C.sub.4 -haloalkyl)carbonyloxy, (C.sub.3 -C.sub.6 -cycloalkyl)carbonyloxy, benzoyloxy, benzylcarbonyloxy, benzyloxy, (C.sub.1 -C.sub.4 -alkoxy)carbonyloxy, (C.sub.1 -C.sub.4 -alkyl-amino)carbonyloxy, di-(C.sub.1 -C.sub.4 -alkyl)-aminocarbonyloxy or C.sub.1 -C.sub.3 -alkylsulfonyloxy; C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy or (C.sub.1 -C.sub.4 -alkyl)carbonyloxy; -C.sub.6 -alkoxy, C.sub.3 -C.sub.6 -alkenyloxy, C.sub.3 -C.sub.6 -alkynyloxy, C.sub.1 -C.sub.6 -alkoxy-C.sub.2 -C.sub.4 -alkoxy, C.sub.3 -C.sub.6 -cycloalkyloxy, amino, C.sub.1 -C.sub.4 -alkylamino, di-(C.sub.1 -C.sub.4 -alkyl)-amino, N-pyrrolidinyl, N-piperidinyl, N-morpholinyl, C.sub.3 -C.sub.6 -cycloalkylamino, di-(C.sub.3 -C.sub.6 -cycloalkyl)-amino, C.sub.3 -C.sub.6 -alkenylamino or C.sub.3 -C.sub.6 -alkynylamino or --N(R.sup.20)--, where R.sup.18 and R.sup.19 are in each case hydrogen or C.sub.1 -C.sub.4 -alkyl and C.sub.3 -C.sub.6 -alkynyl, C.sub.1 -C.sub.6 -alkoxy or C.sub.3 -C.sub.6 -alkenyloxy,
The invention additionally relates to defoliation of plants, defoliation of plants, which contain the compounds I as active substances, and/or defoliation of plants using the compounds I, compositions for the desiccation and/or defoliation of plants using the compounds I, and also
In the earlier German Application DE-A 43 23 916, inter alia, 2-phenylpyridines of the compound I type are described as herbicides and as compounds having desiccant/defoliant activity. Suitable choice of the substituents results, inter alia, in compounds of the formula IIa ##STR4## where R.sup.2 ' is halogen, cyano, nitro, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy, C.sub.1 -C.sub.4 -alkylthio or C.sub.1 -C.sub.4 -haloalkylthio; hydroxycarbonyl, halogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -haloalkyl, C.sub.1 -C.sub.4 -alkoxy, C.sub.1 -C.sub.4 -haloalkoxy, C.sub.1 -C.sub.4 -alkylamino, di-(C.sub.1 -C.sub.4 -alkyl)-amino, C.sub.1 -C.sub.4 -alkylthio, C.sub.1 -C.sub.4 -haloalkylthio or (C.sub.1 -C.sub.4 -alkoxy)carbonyl; bonded, inter alia, via --CO--, --CH.sub.2 --CH(halogen)--CO-- or --C.dbd.C(R.sup.11)--CO--.
EP-A 548 593 additionally discloses that compounds of the formula IIb ##STR5## where Het is various heterocycles and Y, inter alia, is a bond, --OCH.sub.2 --, --OCH(C.sub.1-4 -alkyl)--, --SCH.sub.2 -- or --S--CH(C.sub.1-4 -alkyl) and R.sup.b is H, OH, halogen, C.sub.1-4 -alkoxy, benzyloxy, C.sub.1-3 -alkylsulfonyloxy or certain radicals --O--CO--R, are herbicidally active.
In addition, DE-A 43 35 810 discloses that 3-phenyluracil derivatives in which the
