Cu/P(4-PVP) stereochemistry in tetralin liquid-phase oxidation I. Effect of the CuCl2/P(4-PVP) on selectivity

摘要: Abstract Cu/P(4-PVP) catalyst was used as for oxidation of tetralin in liquid phase. The prepared by reaction a Cu(II) salt with 4-vinylpyridine-co-divinylbenzene polymer receptor and characterized solid 1 H 13 C NMR, XPS, FTIR, ESR spectroscopies, chemical pure tetralin. That information to gain insight into the stereochemistry active site needed orient toward tetralone production. It found that Cu coordination pyridine critical influencing peroxy-radical catalytic reaction, polyvinylpyridine able limit autothermal oxidation. center is postulated be based on (Cu 2+ –Cu + )-pyridine distorted tetrahedric structure modified oxireduction reactions
