Abstract

N-(Phenyl)-tetrahydroindazole derivatives of the general formula Ia and Ib ##STR1## where R.sup.1 is halogen; PA1 R.sup.2 C.sub.1 -C.sub.6 -alkoxycarbonyl-C.sub.3 -C.sub.5 -alkenyl or C.sub.1 -C.sub.3 -alkyl which is substituted in the 1- or 2-position by C.sub.1 -C.sub.6 -alkoxycarbonyl or a 5-or 6-membered saturated or monounsaturated heterocycle which contains one oxygen or sulfur as heteroatom and can be substituted by rom one to four C.sub.1 -C.sub.4 -alkyls, and PA1 R.sup.3 is C.sub.2 -C.sub.7 -alkyl, C.sub.3 -C.sub.6 -C.sub.3 -C.sub.6 -alkynyl, C.sub.1 -C.sub.6 -alkoxycarbonyl-C.sub.3 -C.sub.5 -alkenyl or C.sub.1 -C.sub.3 -alkyl which is substituted in the 1-or 2-position by C.sub.1 -C.sub.6 -alkoxycarbonyl or a 5- or 6-membered saturated or monounsaturated heterocycle which contains one oxygen or sulfur as heteroatom and can be substituted by from one to four C.sub.1 -C.sub.4 -alkyls, their manufacture and their use.
