Novel Hybrid Thioamide Ligand Supported Copper Nanoparticles on SBA-15: A Copper Rich Robust Nanoreactor for Green Synthesis of Triazoles and Tetrazoles in Water Medium

Immobilized Cu(0) nanoparticles on montmorillonite-modified with benzalkonium chloride (MMT-BAC@Cu(0)): as an eco-friendly and proficient heterogeneous nano-catalyst for green synthesis of 5-substituted 1H-tetrazoles

“…All the products were characterized by comparing their melting points with those reported in the literature 16,17,20,[40][41][42] and NMR spectroscopy (see ESI †). The catalytic performance of MMT-BAC@Cu(0) and the use of DES as a green solvent were compared with some previously reported methods to evaluate the present protocol according to other reported 5-substituted 1H-tetrazole derivatives synthesis methods.…”

Nanomaterial catalyzed green synthesis of tetrazoles and its derivatives: a review on recent advancements

“…It was reported that aer eleven successful runs of tetrazole synthesis only 0.6 wt% of Cu species leached in solution. 79 Another nano-catalyst Cu(II)-DCC-CMK-3 was synthesized using SBA-15 as a solid template. The synthesis of Cu(II)-DCC-CMK-3 was achieved via multi-step process as depicted in Scheme 8.…”

Recent Advances in Copper-Based Solid Heterogeneous Catalysts for Azide–Alkyne Cycloaddition Reactions

“…Mesoporous silica, either as Mobil Composition of Matter (MCM-41), Santa Barbara Amorphous (SBA-15), or mesoporous silica materials (KIT-5), are solid supports that provide vast surface areas, making immobilized active species more accessible for substrates during catalytic reactions [59][60][61]. Pourhassan et al [62] functionalized mesoporous SBA-15 silica by thioamide groups to be applied as a recyclable catalyst for the CuAAC reaction (Figure 5). In this context, the channels of SBA-15 were modified with tris(2-aminoethyl)amine (TAEA) groups and then reacted with S 8 and phenylacetylene to form thioamide groups.…”
