1-Heterocyclyl:oxy-2-triazolyl or imidazolyl ethane derivs. - useful as fungicides, esp. against mildews

摘要

Azole derivs. of formula (I), their acid salts and metal complexes are new. In (I) A is 1-6C alkyl or aryl, opt. substd. by one or more halo, 1-4C alkyl, alkoxy, alkoxysulphonyl or haloalkyl, by nitro, cyano or phenyl (itself opt. substd.). X is methine or nitrogen. Het is an aromatic heterocycle, opt. substd. by one or more halo, 1-4C alkyl or haloalkyl, nitro or cyano. They are prepd. e.g. by reacting the corresp. alkoxide with a Het-halide. (I) are pesticides, esp. fungicides, useful in plant protection, particularly for control of true mildews which are resistant to benzimidazole-type fungicides. They can also be used in wood- treating compsns. and paints, or as preservatives.
