4-Alkenylaminocarbonyl- and 4-alkinylaminocarbonyl-1-phenyl-5-pyrazolamines

Abstract

A 5-aminopyrazole of the formula ##STR1## in which R.sup.1 represents alkoxycarbonyl, alkenyloxycarbonyl, alkinyloxycarbonyl, alkenylaminocarbonyl or alkinylaminocarbonyl and R.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7, which are identical or different, represent hydrogen, halogen, cyano, nitro, alkyl, alkoxy, alkylsulphonyl, alkoxycarbonyl or a radical --(X)n--R.sup.8 wherein X represents oxygen, sulphur, sulphinyl or sulphonyl, n represents 0 or 1 and R.sup.8 represents halogenoalkyl, with the proviso that at least one of the radicals R.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 represents a radical --(X).sub.n --R.sup.8, but R.sup.1 does not represent cyano if R.sup.1 represents trifluoromethyl. These compounds are intermediates useful in the preparation of herbicidally active substituted 5-acylamino-1-phenylpyrazoles.
