Abstract: Preparation of 4-nitro-5-mercaptoimidazoles of the formula I in which the radicals R denotes alkyl, alkoxyalkyl, cycloalkyl, aryl, arylalkyl or alkylaryl; R denotes hydrogen, alkyl, cycloalkyl, aryl, arylalkyl or alkylaryl and R denotes alkyl, cycloalkyl, aryl, arylalkyl, alkylaryl or a heterocyclic or heteroaromatic radical as well as hydrogen or a counterion of the corresponding thiolate where the organic radicals mentioned can still carry inert substituents under the reaction conditions, by reacting dinitroimidazoles of the formula II in which R and R have the abovementioned meaning, with mercapto compounds of the formula III R -SH in which R denotes hydrogen, alkoxyalkyl, alkyl, cycloalkyl, aryl, arylalkyl, alkylaryl or a heterocyclic or heteroaromatic radical, in a solvent or diluent at a pH of at least 4 and isolating the products in a manner known per se.

Abstract: Imidazole-4(5)-monocarboxylic acids and their salts or betaines are prepared by reacting an imidazole with carbon dioxide and an alkali metal carbonate, an alkali metal bicarbonate and/or an alkali metal hydroxide at from 140 DEG to 230 DEG C. and under from 2 to 350 bar and, if desired, then reacting the product with an acid. The imidazole-4(5)-monocarboxylic acids which can be prepared by the process of the invention are useful starting materials for the preparation of dyes, crop protection agents and drugs.

Abstract: 5,6-Dihydro-2H-thiopyran-3-carboxaldehydes of the formula where R denotes hydrogen or methyl, are prepared by a method in which acrolein or crotonaldehyde is reacted with hydrogen sulfide in a mineral oil whose boiling point is higher than those of the starting materials and of the end product, and the 5,6-dihydro-2H-thiopyran-3-carboxaldehyde is obtained by distillation. These aldehydes are important intermediates for the preparation of some crop protection agents.

Abstract: 4-Alkylimidazole derivatives of the formula I I where R1 is C1-C4-alkyl, R2 is chlorine or bromine and R3 is an -OR4 or -NR5R6 group in which R4 is C1-C4-alkyl, R5 is hydrogen or C1-C4-alkyl and R6 is C1-C4-alkyl or is phenyl which is unsubstituted or substituted by 1 or 2 halogen atoms, and its salts, their preparation and their use as nitrification inhibitors.
