Metathesis of cardanol over Ru catalysts supported on mesoporousmolecular sieve SBA-15

Popis výsledku v původním jazyce

tThe Hoveyda?Grubbs type Zhan catalysts (ZC) and Grubbs second generation catalyst (GII) were immo-bilized on SBA-15 mesoporous molecular sieve by non-covalent interactions and phosphine linkers,respectively. Both hybrid catalysts proved to be highly active and selective in cardanol metathesis andcardanol cross-metathesis with ethene and cis-1,4-diacetoxy-2-butene (DAB). GII/SBA-15 was less activethan ZC/SBA-15, however, Ru leaching was significantly lower for GII/SBA-15 (0.5%) than for ZC/SBA-15(2.5%).In ethenolysis of cardanol, 3-(non-8-enyl)phenol was isolated as a major product. In cross-metathesis with DAB 9-(3-hydroxyphenyl)non-2-enyl acetate and non-2-enyl acetate were formed withhigh selectivity. Easy catalyst?product separation and low Ru leaching provide the products (applicableas detergent precursors and fragrance and flavor agents) free from the catalyst residue.
