abstract |
Compounds of formula (I) and their salts, in which A is a group of formula (A1), L is a Q-R group, and R, R<1>, R<2>, R<3>, m, Q, X, Y and Z are defined as in claim 1, are suitable as herbicides and plant-growth regulators. They can be prepared in a manner similar to known processes according to claim 5. Amines of formula (II), in which R = H and L = SR, can also be obtained from anilines (V) by chlorination, reacting with compound (VI), ACH2L, with the formation of azasulphonium salt (VII) and basic transposition (see claim 6). |
