| titleOfInvention | 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 |
| abstract | FIELD: chemistry. n 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. n 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. n 2 cl, 6 ex |
