Popis:	In reaction of 5, 8-dihydroxy-2, 3-dichloro-6-ethyl-7-ethoxy-1,4-naphthoquinone and 6-tert-butyl-5,8-dihydroxy-2,3-dichloro-l,4-naphthoquinone proceeding on the surface of molecular sieves, calcium phosphate and carbonate, neutral alumina, or magnesium silicate with nucleophilic reagents (methanol, 2-methoxyethanol, monomethyl ethers of di- and triethylene glycols) activated with fluoride anion the yield of products decreased in this nucleophiles series. The most active catalysts among sorbents are alumina and magnesium silicate. All the sorbents are also efficient catalysts of alkoxy groups interchange.
