Abstract
The invention relates to imidazole-5-carboxylic acid derivatives in which the imidazole ring is substituted in the 1-position by a 2,6-dialkylphenyl radical and which have the formula ##STR1## in which X=O, S or N. The compounds are obtained from appropriately substituted bisformyl esters, either by reacting the latter with formamide or with ammonium acetate or by subjecting aminomethylene compounds prepared from the bisformyl esters to an intramolecular condensation reaction. The new substances can be used as biocides, in particular herbicides, fungicides and growth regulators.
