    Abstract: - 10 - O.Z. 0050/36,280 Organic condensation reactions are carried out at elevated temperatures by a method in which the starting material or materials are fed in, in gaseous form, at the bottom of a reactor charged with a mineral oil having a boiling point of not Less than 150.degree.C, or are fed in in liquid form, at the bottom of the reactor, and the mineral oil is kept at a temperature which is no lower than the boiling points, of the starting materials introduced as liquids, which correspond to the partial pressures, of the said starting materials, resulting at the bottom of the reactor, and the product is taken off, in gaseous form, at the top of the reactor.

    Abstract: 4-Nitro-5-imidazolyl ethers and thioethers of the formula I (I) where R1 is alkyl, alkoxyalkyl, cycloalkyl, aryl, aralkyl or alkylaryl, R2 is hydrogen, alkyl, cycloalkyl, aryl, aralkyl or alkylaryl, R3 is alkyl, cycloalkyl, aryl, aralkyl, alkylaryl or a heterocyclic or heteroaromatic radical or a counter-ion of the corresponding alcoholate or thiolate or, where X is sulfur, R3 is hydrogen, and X is oxygen or sulfur, and the stated organic radicals may furthermore carry substituents which are inert under the reaction conditions, are prepared by reacting a dinitroimidazole of the formula II (II) with an alcohol or thiol of the formula III R3-XH (III) in a solvent or diluent at a pH of the from 4 to 16.
