Synthesis and characterization of magnetic Fe3O4@Creatinine@Zr nanoparticles as novel catalyst for the synthesis of 5-substituted 1H-tetrazoles in water and the selective oxidation of sulfides with classical and ultrasonic methods

Synthesis and Catalytic Application of MTsCOO‐Cu as a Melamine‐Based Metal‐Organic Framework in Facile Preparation of the 5‐Substituted‐1H‐Tetrazoles

“…In comparison of the MTsCOO-Cu MOF with already reported MOFs containing copper nodes and tritpopic linkers, may concluded that, the MTsCOO-Cu MOF with tritopic melamine-based MTsCOOH ligand may forms an isoreticular framework as Cu 3 (TATB) 2 (known as PCN-6' MOF) with a melamine-based 4,4',4''-(1,3,5-triazine-2,4,6-triyl) tribenzoic acid [47] 2 3 78 220-222, 217-219 [47] 3 3.5 75 258-260, 260-265 [48] 4 4 82 270-272, 268-270 [32] 5 7 70 233-234, 234-236 [48] 6 6 85 160-161, 159-160 [33] ChemistrySelect Oily, Oily [32] 11 5 77…”

A new samarium complex of 1,3-bis(pyridin-3-ylmethyl)thiourea on boehmite nanoparticles as a practical and recyclable nanocatalyst for the selective synthesis of tetrazoles

“…Regarding the fact that selective and reusable catalysts are the main principle of green chemistry, herein a new complex of samarium was investigated using 1,3-bis(pyridin-3-ylmethyl)thiourea on boehmite nanoparticle (Sm-bis(PYT)@boehmite) as a stable, practical, and recyclable nanocatalyst in the homoselective synthesis of 5-substituted 1H-tetrazole derivatives in PEG-400 as a green solvent. Due to the act that one of the principles of green chemistry is to use reusable, cheap and sustainable catalysts, different heterogeneous supported catalysts based on mesoporous materials 45 – 48 , MOF structures 49 , boehmite 50 , 51 , carbon materials 52 , polymers 53 , magnetic particles 54 – 58 etc. have been reported as catalysts.…”

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

“…[15][16][17] These reactions were carried out by using various catalysts, according to the reports. [18][19][20][21][22][23] Despite their usefulness, some of these methods suffer from several disadvantages, such as long reaction times, expensive and toxic reagents, and difficulty in separating and reusing the catalyst. Moreover, many catalysts need to use dimethylformamide (DMF) as a solvent during the reaction, while the green chemistry 24 perspective insistently looks forward to developing safe and clean processes in the presence of solvents and green catalysts.…”
