    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.

    摘要： The present invention relates to a method of working up an aluminum-containing reaction product from the production of isopulegol by cyclization of citronellal in the presence of complex compounds, comprising at least one ligand of the formula (I), where R1, R2, R3 are chosen from hydrogen, halogen, nitro, C1-C8-alkyl, C1-C8-alkoxy, di(C1-C4-alkyl)amino and aryl; R4, R5 are chosen from halogen, nitro, C1-C8-alkyl, C1-C8-alkoxy, di(C1-C4-alkyl)amino, aryl or heteroaryl; in which a) the reaction product is subjected to distillative separation to obtain an isopulegol-enriched top product and an isopulegol-depleted bottom product and b) the ligand of the formula (I) is separated off from the bottom product. Moreover, the invention relates to a method of producing isopulegol, and to a method of producing menthol.
