new magnetically reusable nanosolid, Fe3O4@PPCA@Pd(0) (PPCA = piperidine-4-carboxylic acid), as a versatile and highly
effective catalyst was fabricated and characterized using transmission and scanning electron microscopies, X-ray diffraction,
thermogravimetric analysis, Fourier transform infrared and energy-dispersive spectroscopies and vibrating sample magnetometry.
This nanosolid shows great catalytic activity for the synthesis of biphenyl compounds in short reaction times and with high yields.
Themagnetic character of this catalyst allows retrieval andmultiple uses without appreciable loss of its catalytic activity. Our system
not only solves the basic problems of catalyst separation and recovery, but also the reactions can be performed in green media.
