Аннотация:A study was conducted on two-phase Wacker oxidation of 1-alkenes (1-hexene, 1-heptene, 1-octene, 1-nonene; 1-docene; and 1-dodecene), catalyzed by water-soluble Pd complexes with cyclodextrines modified by nitrile-containing ligands. Metal complexes with ability of molecular recognition considerably increase reaction rate and lower the apparent reaction activation energy. The substrate selectivity of suggested systems was determined: maximum activity was achieved for 1-heptene.
