Molybdenum carbonyl grafted onto silicate intercalated cobalt–aluminum hydrotalcite: A new potential catalyst for the hydroformylation of octene

•First example of molybdenum carbonyl based catalyst for hydroformylation.•Introduction of Mo(CO)6 on CoAl–HT helps on cooperative mechanism.•Heterogenization evident from 29Si MAS-NMR and FT-IR•Catalyst showed 80% olefin conversion and branched aldehyde selectivity.

We present the first example of molybdenum carbonyl grafted on diaminosiloxane-functionalized cobalt–aluminum hydrotalcite (CA–HTSi–DA–Mo) as a promising catalyst for the hydroformylation of olefins. The catalyst showed 80% conversion with selective formation of branched aldehyde. About 70% of the catalytic activity retains even after three cycles.
