Abstract:
The present invention relates to novel macrocyclic lactones, to processes for their preparation and to their use as fragrances and also to products comprising the novel macrocyclic lactones.
Abstract:
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.
Abstract:
Use of a composition comprisinga) at least one imidazolium salt of the formula I where R1 and R3 are each, independently of one another, an organic radical having from 1 to 20 carbon atoms, R2, R4 and R5 are each, independently of one another, an H atom or an organic radical having up to 20 carbon atoms and A− is an anion, and b) at least one carboxylate selected from among those of the formula IIa of the formula IIb and the formula IIc where the radicals R1 to R5 are as defined above, as operating material in industrial apparatuses.
Abstract:
Process for preparing homoallyl alcohols by catalyzed reaction of alkenes with aldehydes or ketones, wherein the reaction is carried out in the gas phase in the presence of noncovalently supported ionic liquid phase catalysts.
