1,1-Diaryl-2-azolylethanes and preparations containing these compounds

Abstract

Substituted ethanols of the general formula ##STR1## in which Ar.sub.1 is a carbocyclic or heterocyclic ring and Az is a triazolyl, benzimidazolyl, pyrazolyl or imidazolyl radical, are reacted with aryl hydrocarbons Ar.sub.2 --H, in which Ar.sub.2 has the same meaning as Ar.sub.1, in the presence of an acidic catalyst, to give 1,1-diaryl-2-azolylethanes. The substances, which, apart from the imidazolyl derivatives, are new, can be used as biocides, in particular fungicides.

Dependencies are inferred from the claim text.
