    • Typical experimental procedure: An aryl halide (10 mmol), methyl acrylate (10 mmol), triethylamine (10 mmol) were added to NMP (15 mL) in a 50 mL flat bottomed flask. The catalyst (0.2 g, 10% Pd/C) was added and the mixture was sonicated and stirred for the specified time at rt in air. Samples were withdrawn at various time intervals and analysed by gas chromatography. The product was identified by comparison with an authentic sample. The ultrasonic bath used for reactions had a frequency of 35 kHz and electric power rating of 85 W

    • Typical experimental procedure for the redeposition of dissolved Pd onto the carbon support: The filtrate from the above reaction was reduced with sodium formate (3 g) under sonication for 10 h. Redeposition was monitored using ICP-AES analysis for Pd content in solution. The catalyst was filtered off and used for successive recycles
