Description	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. 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.
