Abstract: Herbicidal cycloalkanapyrazoles of the formula: ##STR1## where N IS 3, 4 OR 5;R.sub.1 is hydrogen or methyl;Q is fluorine, chlorine, bromine or iodine;X is fluorine, chlorine, bromine, iodine, cyano, methoxy or nitro;Y is hydrogen, fluorine, or chlorine;Z is hydrogen or fluorine; andV is hydrogen, fluorine, chlorine or methoxyWith the proviso that(a) when n is 5, R.sub.1 must be hydrogen, Q must be chlorine or bromine, Z and V must both be hydrogen and Y must be hydrogen or fluorine;(b) when n is 3 or 4 and Q is fluorine or iodine, R.sub.1, Z and V must be hydrogen and Y must be hydrogen or fluorine;(c) when n is 3 and R.sub.1 is methyl, Q must be chlorine or bromine, Y must be hydrogen or fluorine and Z and V must both be hydrogen; and,(d) when V is other than hydrogen, X must be fluorine, chlorine or bromine and Z must be hydrogen.

Abstract: This invention relates to a novel process for preparing indazoles by the reaction of phosgene with indazolones. The resulting indazoles are useful as herbicidal compounds.
