- N-phenylpyrrolidines
-
The 1-(3,5-bis-trifluoromethylphenyl)-2-thioxopyrrolidine-4-carboxylic acid derivatives of the formula I below are suitable for protecting crop plants against the phytotoxic action of herbicides and for regulating the plant growth. The 1-(3,5-bis-trifluoromethylphenyl)-2-thioxopyrrolidine-4-carboxylic acid derivatives are those of the formula I STR1 wherein A is --COOR1, --COSR1, --COO? M≈, --CONR2 R3 or --COCl; R1 is hydrogen, C1 -C4 alkyl, C2 -C6 alkenyl or C2 -C6 alkynyl; R2 and R3 independently of one another are hydrogen, C1 -C4 alkyl or C3 -C7 cycloalkyl; or R2 and R3 together with the nitrogen atom to which they are bonded are a saturated 3- to 7-membered heterocycle which can contain an additional hetero atom selected from the group comprising O, N and S and which is unsubstituted or up to trisubstituted by C1 14 C4 alkyl; and M≈ is the equivalent of an alkali metal cation or an alkaline earth metal cation or HN≈ (R2)3, and their isomers in optically pure or enriched form.
