Abstract
3-phenylpropionic acid derivatives of the general formula I ##STR1## where R.sup.1 is hydrogen or halogen, R.sup.2 is halogen, R.sup.3 is unsubstituted or halogen-, C.sub.1 -C.sub.4 -alkoxy- or C.sub.1 -C.sub.4 -alkylthio-substituted C.sub.2 -C.sub.6 -alkyl, C.sub.5 -C.sub.7 -cycloalkyl-substituted C.sub.1 -C.sub.6 -alkyl, further C.sub.5 -C.sub.7 -cycloalkyl, C.sub.3 -C.sub.6 -alkenyl or C.sub.3 -C.sub.6 -alkynyl or, together with R.sup.4, a C.sub.2 -C.sub.4 -alkylene chain, R.sup.4 is hydrogen or unsubstituted or halogen-, C.sub.1 -C.sub.4 -alkoxy-, C.sub.1 -C.sub.4 -alkylthio- or C.sub.5 -C.sub.7 -cycloalkyl-substituted C.sub.1 -C.sub.6 -alkyl; C.sub.3 -C.sub.7 -cycloalkyl; unsubstituted or halogen-substituted C.sub.3 -C.sub.6 -alkenyl or C.sub.3 -C.sub.6 -alkynyl or halogen or R.sup.4, together with R.sup.5 and the carbon atom of this substituent, is C.sub.3 -C.sub.6 -cycloalkyl which may be interrupted by an oxygen or a sulfur atom, R.sup.5 is unsubstituted C.sub.1 -C.sub.6 -alkyl or halogen-, C.sub.1 -C.sub.4 -alkoxy- or C.sub. 1 -C.sub.4 -alkylthio-substituted C.sub.2 -C.sub.6 -alkyl; cyano or acyl (COR.sup.6) or alkoxycarbonyl (CO.sub.2 R.sup.7), R.sup.6 denoting C.sub.1 -C.sub.6 -alkyl or, together with R.sup.4, a C.sub.3 -C.sub.5 -alkylene chain and R.sup.7 denoting unsubstituted or halogen-, C.sub.1 -C.sub.4 -alkoxy- or C.sub.1 -C.sub.4 -alkylthio-substituted C.sub.2 -C.sub.6 -alkyl or unsubstituted or C.sub.5 -C.sub.7 -cycloalkyl-substituted C.sub.1 -C.sub.6 -alkyl, further C.sub.5 -C.sub.7 -cycloalkyl, C.sub.3 -C.sub.6 -alkenyl or C.sub.3 -C.sub.6 -alkynyl, with the proviso that R.sup.1 and R.sup.4 do not simultaneously denote hydrogen when R.sup.5 is cyano or CO.sub.2 R.sup.7, processes for their manufacture, and their use as herbicides.
