چکیده
|
Lafe0.57co0.38pd0.05o3 perovskite-type oxide catalysts were synthesized via flash combustion method. then,their structural and textural properties were studied. depending on the thermal treatment,amorphous or crystalline materials with different particle sizes were obtained. the catalytic activity of these systems was investigated in suzuki-miyaura and sonogashira cross-coupling reactions. mechanistic studies demonstrated that the materials operate following release and catch mechanism. ingress and egress of palladium in perovskite systems constitute a driving force for the preparation of new chemicals with low metal contamination.
