Synthesis of carboranyl amides catalyzed by recyclable Pd (0) nanoparticles supported on carbon nanotubes (CNTs)

Palladium (0) nanoparticles with small size and narrow size distribution were synthesized conveniently and supported on CNTs. The supported nano-Pd0 was found to be a highly efficient and recyclable catalyst for the aminocarboranylation reaction of aryl halide. Thus, a series of carboranyl amides, 1-R-2-[CH2NHC(=O)Ar]-1,2-C2B10H10 (R = H, Me; Ar = C6H5, 4-Me-C6H5, 4-MeO-C6H5 and 2-C5NH4), were synthesized and fully characterized. The catalyst was recyclable at least three times with sustained activity.
