Silica-supported NiO nanocomposites prepared via a sol–gel technique and their excellent catalytic performance for one-pot multicomponent synthesis of benzodiazepine derivatives under microwave irradiation
Heterogeneous and versatile NiO–SiO2 NCs were synthesized by a sol–gel technique and used as a catalyst for the one-pot multicomponent synthesis of benzodiazepine derivatives (4a–u) from a mixture of o-phenylenediamine, aromatic aldehydes and dimedone undermicrowaveirradiation. Tetraethyl orthosilicate (TEOS) was used as a source of SiO2 for the creation of the NiO–SiO2 NCs. This catalytic protocol

novel magnetic heterogeneous nanocatalyst CoFe2O4@SiO2@NH-NH2-PCuW was synthesized and characterized. This powerfulcatalyst possesses Bronsted and Lewis acid properties. The presence of Cu enhances the acidity of this catalyst because of the increase in the electron deficiency of polyoxometalate. It was successfully applied for the easy and efficient one-pot synthesis of 1,4-benzodiazepine derivatives
