METHOD OF PRODUCING SULFOXIDES THROUGH CATALYTIC OXIDATION OF THIOETHERS Russian patent published in 2009 - IPC C07C315/02 C07C317/14 B01J23/06 B01J27/25 B01J31/06

Abstract RU 2374225 C1

FIELD: chemistry.

SUBSTANCE: invention relates to organic chemistry, more specifically to a method of producing sulfoxides through catalytic oxidation of thioethers in the presence of hydrogen peroxide, distinguished by that, the catalyst is in form of zinc compounds such as: zinc salts Zn(NO₃)₂·6H₂O or Zn(CH₃COO)₂·2H₂O, zinc complex compound Zn(salen), coordination polymers based on complex zinc compounds such as homochiral microporous coordination polymers with composition: [Zn₂BDC·(L-Lac)·DMF]·(DMF)_x, where: BDC - dianion of terephthalic acid, L-Lac - dianion of lactic acid, DMF - dimethylformamide; [Zn₂camph₂bipy]·3DMF·H₂O, where H₂camph - (+)-camphoric acid, biry -4,4'-bipyridyl; [Zn₂(bpdc)(R-man)(dmf)]·4DMF·H₂O, where: H₂bpdc - 4,4'-biphenyldicarboxylic acid, R-man - R- mandelic acid; [Zn₂camph₂bpe]·5DMP-H₂O, where: bpe - trans-bis(4-pyridyl)ethylene.

EFFECT: method is designed for producing sulfoxides with high conversion and selectivity, which are widely used in synthesis of organic compounds, including biologically active compounds.
