Abstract

The invention pertains to phenylcarbamates of formula (I), wherein X is a direct bond, O or NR.sup.a ; Z is O, S or NR.sup.b- ; R.sup.1 is hydrogen, alkyl or alkyl halide; R.sup.2 is substituted methyl or optionally substituted alkyl, alkenyl, alkinyl or cycloalkyl; R.sup.3 is optionally substituted alkyl, alkenyl or alkinyl; R.sup.4 is alkyl, alkenyl or alkinyl and, if X is NR.sup.a, hydrogen also; R.sup.5 is hydrogen or optionally substituted alkyl, alkenyl, alkinyl, alkyl carbonyl or alkoxy carbonyl. The invention also pertains to methods for their preparation and agents containing them.
