Abstract
1-Trifluoromethyl-1-nitro-2-alkoxy-2-aryl-ethanes of the formula ##STR1## in which R.sup.1 represents a straight-chain or branched alkyl radical and R.sup.2 represents an optionally substituted aryl or hetaryl radical, their preparation from an aldehyde of the formula R.sup.2 --CHO, an alcohol of the formula R.sup.1 --OH and trifluoromethylnitromethane in the presence of a compound containing basic groups and antimycotic agents containing these compounds.
Claims4
1-Trifluoromethyl-1-nitro-2-alkoxy-2-arylethanes of the formula (I) ##STR8## in which R.sup.1 represents a straight-chain or branched alkyl radical having 1-6 carbon atoms and
- R.sup.2 represents a substituted or unsubstituted 5 or 6 membered hetaryl radical, having one or two heteroatoms, which can be the same or different, and which are selected from the group consisting of nitrogen, oxygen and sulfur;
- and wherein the substituents are one or more substituents which can be the same or different and which are selected from the group consisting of 1 to 3 halogen atoms, 1 or 2 nitro groups, 1 or 2 alkoxy groups each having from 1-6 carbon atoms, 1 or 2 HCO groups and the radical ##STR9## wherein R.sup.1 has the meaning defined above.
An antimycotic agent, which contains 1-trifluoromethyl-1-nitro-2-alkoxy-2-arylethanes of the formula (I) ##STR10## in which R.sup.1 represents a straight-chain or branched alkyl radical having 1-6 carbon atoms and
- R.sup.2 represents a substituted or unsubstituted 5 or 6 membered hetaryl radical, having one or two heteroatoms, which can be the same or different, and which are selected from the group consisting of nitrogen, oxygen and sulfur;
- and wherein the substituents are one or more substituents which can be the same or different and which are selected from the group consisting of 1 to 3 halogen atoms, 1 or 2 nitro groups, 1 or 2 alkoxy groups each having from 1-6 carbon atoms, 1 or 2 CHO groups and the radical ##STR11## wherein R.sup.1 has the meaning defined above and, optionally, customary additives.
The method of combating undesired fungi, in which a composition comprising 1-trifluoromethyl-1-nitro-2-alkoxy-2-arylethanes of the formula (I) ##STR12## in which R.sup.1 represents a straight-chain or branched alkyl radical having 1-6 carbon atoms and
- R.sup.2 represents a substituted or unsubstituted 5 or 6 membered hetaryl radical, having one or two heteroatoms, which can be the same or different, and which are selected from the group consisting of nitrogen, oxygen and sulfur;
- and wherein the substituents are one or more substituents which can be the same or different and which are selected from the group consisting of 1 to 3 halogen atoms, 1 or 2 nitro groups, 1 or 2 alkoxy groups each having from 1-6 carbon atoms, 1 or 2 CHO groups and the radical ##STR13## wherein R.sup.1 has the meaning defined above, and also optionally comprising customary additives is applied to said fungi or a habitat of said fungi.
