    • In a typical reaction, the substrate (10 mmol) was dissolved in methanol (10 mL) to which ammonium formate (30 mmol) was added as a hydrogen donor along with the catalyst (PdMCM-41; 50 mg). The reaction mixture was then refluxed at 343 K for several minutes to a few hours depending on the nature of the substrates. The progress of the reaction was monitored by TLC, and the products were analyzed using GC (Eshika) fitted with an OV-17 column. After completion of the reaction, the catalyst was recovered for the recycling studies by simple filtration, washed several times with acetone followed by distilled water, then activated at 373 K for 6 h.
