Covalent grafting of cobalt carbonyl cluster on functionalized mesoporous SBA-15 molecular sieve and its applications towards hydroformylation of 1-octene

Cobalt carbonyl cluster was anchored through a facile route on the surface of organo-functionalized SBA-15 molecular sieve by post-synthetic approach. The successful grafting of organofunctional ligand and cobalt carbonyl cluster was evident thorough Si-29-MAS NMR, C-13-MAS NMR and Fr-IR studies. The resultant cobalt clusters anchored functionalized SBA-15 material (SBA-15-RCo) showed promising catalytic activity on hydroformylation of 1-octene (97% conversion) with excellent selective towards hydroformylated products (90%).
