Abstract

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method for preparing bicyclic and polycyclic ketones and their derivatives using oxidation reaction of 1,2-dihydronaphthalene, acenaphthylene, indene or norbornene and their derivatives to corresponding ketones with nitrous oxide or its mixture with inert gas. Process is carried out in liquid phase at temperature 150-250 C and under pressure of nitrous oxide 1-100 atm. As inert gas exhaust reaction gases are used preferably and reaction can be carried out in the presence of catalyst and solvent. Invention provides the enhancement of selectivity of production of end products and improved economical indices of process. EFFECT: improved preparing method. 13 cl, 2 tbl, 26 ex
