    摘要: A process for the preparation of imidazoles which are substituted with p-nitrophenyl in the 2- and/or 4- and/or 5-position and may carry additional substituents, by reacting imidazoles which are substituted by phenyl in the 2- and/or 4- and/or 5-position and may carry additional substituents with mixtures of sulfuric acid and nitric acid, wherein the reaction is carried out in the presence of urea.

    摘要: Ketones of the formula II where A is optionally alkyl-substituted C2-C12-alkanediyl, R1 and R2 are each, independently of one another, C1-C6-alkyl, or R1 and R2 together form optionally alkyl-substituted C3-C10-alkanediyl, and R3 is hydrogen or C1-C6-alkyl, are prepared by reacting a cyclic olefin of the formula I with dinitrogen monoxide to form the ketone of the formula II. The ketone of the formula II can be further hydrogenated to form the saturated ketone of the formula III. Macrocyclic ketones of the formula III, e.g. muscone, are sought after as fragrances.
