Jafari, Fariba; Ghorbani-Choghamarani, Arash; Hasanzadeh, Neda published the artcile< Guanidine complex of copper supported on boehmite nanoparticles as practical, recyclable, chemo and homoselective organic-inorganic hybrid nanocatalyst for organic reactions>, Category: alcohols-buliding-blocks, the main research area is copper immobilized guanidine modified boehmite nanoparticle preparation thermal stability; nitrile copper guanidine modified boehmite nanoparticle catalyst homoselective cycloaddition; phenyl tetrazole preparation; sulfide copper guanidine modified boehmite nanoparticle catalyst chemoselective sulfoxidation; sulfinyl preparation.
Boehmite (BO) nanoparticles (NPs) were prepared via the injection of aqueous NaOH solution to aqueous aluminum nitrate solution at room temperature Afterwards, a new complex of copper was immobilized on BO-NPs (Cu-Guanidine@BO-NPs). This heterogeneous nanocatalyst was used as a practical, recyclable, chemo and homoselective nanocatalyst in the organic processes, i.e. the preparation of tetrazole five-membered heterocycles and chemoselective sulfoxidation of sulfides using H2O2 as oxidant. In this sense, the prepared nanocatalyst was characterized by AAS, N2 adsorption-desorption isotherms, WDX, EDS, SEM, and TGA techniques. The reusability of this catalyst was investigated in the described organic reactions for several runs without notable loss of its catalytic activity. Moreover, all of the tetrazole and sulfoxide derivatives were isolated in high Turn Over Number (TON) and Turn Over Frequency (TOF) numbers indicating the high activity and selectivity of Cu-Guanidine@BO-NPs in the described reactions.
