Abstract: | Ligand-free solid-supported nano and microparticles of Pd(0) (SS-Pd) were used as a heterogeneous catalyst in carbon-heteroatom bond formation reactions. Nitro substituted aryl halides reacted with oxygen, sulfur, and nitrogen nucleophiles to afford the corresponding products in good yields. A one-pot sequential cross coupling and nitro-reduction was also performed using the same SS-Pd catalyst to access amine substituted carbon-heteroatomic molecules. In addition, SS-Pd could be recycled up to seven runs without a significant loss of catalytic activity. |
