In this work, in the first stage, boehmite nanoparticles were easily fabricated via addition of NaOH solution to a solution of Al(NO3)(3).9H(2)O at room temperature in water. Then, nickel-dithizone catalyst was supported on boehmite nanoparticles (Ni-dithizone@boehmite). Ni-dithizone@boehmite is a low-cost, nontoxic, and recoverable catalyst, which provides an environment friendly reaction conditions. In the second stage, catalytic activity of this catalyst was studied in the synthesis of polyhydroquinoline derivatives and selective oxidation of sulfides to sulfoxides. The reactions not require very high temperatures or inert atmosphere. The developed heterogeneous catalyst could be easily separated by centrifugation and recycled for several runs without leaching of Nickel from the surface of the catalyst or significant loss of its catalytic activity.
