Abstract

Fungicidally active carbamoyloxythiophene derivatives of the formula ##STR1## in which R.sup.1 represents alkyl, alkoxyalkyl, alkylthioalkyl, fluoroalkyl, cyanoalkyl, alkenyl, alkynyl, or cycloalkyl, PA0 R.sup.2 represents alkyl, optionally substituted furyl or optionally substituted phenyl, PA0 R.sup.3 represents aliphatic or carbocyclic cyanoalkyl, the ##STR2## radical or the --A.sup.2 --CO--OR.sup.6 radical, where A.sup.1 represents an alkylene radical, PA1 A.sup.2 represents an alkylene radical or denotes a direct bond, PA1 R.sup.4 and R.sup.5, independently of one another, represent alkyl, or PA1 R.sup.4 and R.sup.5, together with the nitrogen atom which they neighbor, form a heterocyclic ring which may contain further hetero atoms and is optionally substituted, and PA1 R.sup.6 represents alkyl, and novel intermediates therefor.
