Abstract:

C–H activation reaction is one of the most challenging reactions in the present scenario. The green synthesis of benzaldehyde from toluene using TBHP in a sustainable amount as an oxidant over indium-incorporated TUD-1 is performed in the present study. In(1)-TUD-1 (In/Si = 1/100 mol ratio) shows 48% toluene conversion and 83% benzaldehyde selectivity using acetic acid as solvent. The catalyst was recyclable up to five times. A plausible reaction mechanism is also proposed based on the characterization results.
