3-PHENOXYPHENYL-CONTAINING 1,3-DIKETONES AS STARTING COMPOUNDS FOR PRODUCING CHELATE COMPLEXES THEREOF WITH COPPER (II) IONS AND METHOD OF PRODUCING 3-PHENOXYPHENYL-CONTAINING 1,3-DIKETONES Russian patent published in 2013 - IPC C07C49/84 C07C45/65 C07C45/68 C07C45/72 

FIELD: chemistry.

SUBSTANCE: invention relates to the chemistry of diphenyl oxide derivatives and specifically to novel 3-phenoxyphenyl-containing 1,3-diketones, intermediate compounds in synthesis of a wide range of biologically active substances of general formula , for example as starting compounds for producing chelate complexes thereof with copper (II) ions of general formula , which have potential for use as extraction agents, analytical reagents of rare-earth elements, vital semiproducts in synthesis of probable biologically active substances. The invention also relates to a method of producing 3-phenoxyphenyl-containing 1,3-diketones, involving reaction of 3-phenoxybenzonitrile with lower alcohols: methanol, ethanol in molar ratio 1:4.245, respectively, in the presence of concentrated sulphuric acid for 7-8 hours, to form alkyl-3-phenoxybenzoate, and subsequent reaction thereof with ketones selected from: acetone, 2-butanone, acetophenone in molar ratio 2.0:1, respectively, in a medium of pure cyclohexane at boiling point thereof in the presence of catalytic amounts of sodium hydride for 2.5-3 hours, followed by extraction of the end product.

EFFECT: wider range of diphenyl oxide derivatives and obtaining 3-phenoxyphenyl-containing 1,3-diketones and chelate complexes thereof with copper (II) ions with high output.
