TETRAHYDROINDAZOLES WITH A PHENYL ETHER STRUCTURE

摘要

N-(Phenyl)-tetrahydroindazole derivatives of the general formula Ia and Ib where R1 is halogen; R2 is C1-C6-alkoxycarbonyl-C3-C5-alkenyl or C1-C3-alkyl which is substituted in the 1- or 2-position by C1-C6-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 C1-C4-alkyls, and R3 is C2-C7-alkyl, C3-C6-alkenyl, C3-C6-alkynyl, C1-C6-alkoxy- carbonyl-C3-C5-alkenyl or C1-C3-alkyl which is substituted in the 1- or 2-position by C1-C6-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 C1-C4-alkyls, their manufacture and their use herbicides.
