Mirzaei-Mosbat, Maryam; Ghorbani-Vaghei, Ramin; Sarmast, Narges published an article in 2019, the title of the article was One-pot synthesis of 4-aryl-NH-1,2,3-triazoles in presence of Fe3O4@SiO2@propyl-HMTA as a new basic catalyst.Formula: C9H9N3 And the article contains the following content:
Hexamethylenetetramine-functionalized magnetic Fe3O4 nanoparticles (Fe3O4@SiO2@Propyl-HMTA) catalyst was prepared and characterized by FT-IR, SEM, TEM, TGA, XRD and VSM. This nanomagnetic catalyst had several advantages such as easier separation, recycling from reaction media due to its heterogeneous nature, higher reactivity and catalytic power due to its enhanced surface area. Further, this catalyst was utilized for the synthesis of 4-aryl-NH-1,2,3-triazole derivs I [Ar = 4-ClC6H4, 2-O2NC6H4, 3-indolyl, etc.] by three-component reaction of aldehydes, nitromethane and sodium azide through Henry condensation and then in situ [3+2] cycloaddition reaction. The experimental process involved the reaction of 4-(p-Tolyl)-1H-1,2,3-triazole(cas: 5301-96-2).Formula: C9H9N3
The Article related to hmta functionalized silica coated iron oxide nanoparticle catalyst preparation, triazole green preparation, aldehyde nitromethane sodium azide henry cycloaddition iron oxide nanocatalyst and other aspects.Formula: C9H9N3
