Novel polystyrene incorporated Palladium (II) catalyst was developed and well characterized. The efficiency of the supported Pd(II) catalytic material was checked for double carbonylation reaction of 2° amines and aryl iodides to their corresponding α-ketoamides under high pressure reaction conditions. The reaction was carried out in 60 psi carbon monoxide pressure. An extensive variety of aryl iodides in combination with 2° amines in presence of carbon monoxide can produce the respective α-ketoamides with superb chemoselectivity. Effect of solvents, bases, time and amount of catalyst for the production of α-ketoamides were reported. This supported Pd(II)complex was highly catalytically active and recyclable. The developed catalytic material was regenerated by filtration. It could be recycled further six times with no such profound loss in its activity.

A novel synthesis of α-ketoamides from Cu-catalyzed aerobic oxidative C(sp3)–C(sp3) bond cleavage of hydrocinnamaldehydes has been developed. Readily available and environmentally benign oxygen is used as the oxidant. This reaction avoids the use of noble metal catalysts or specialized oxidants, and chemoselectively yields α-ketoamide. Moreover, based on various control experiments, a reasonable mechanism is proposed.
