of the silver nanoparticles (Ag NPs) onto the material. The silver nanoparticle was decorated over the HMP‐2 to prepare the corresponding catalyst (Ag‐HMP‐2). The characterization of the newly produced material has been conducted by N2 adsorption/desorption studies, XPS, FE‐SEM, transmission electron microscopy (TEM) and Powder X‐ray diffraction (PXRD) methods. This microporouscatalyst has spectacular

From readily available propargylic amines, 1,2,5-trisubstituted imidazoles are efficiently obtained through a cascade reaction catalyzed by AgOTf or promoted by molecular iodine. The AgOTf-catalyzed reaction involves nucleophilic addition of propargylic amine to ketenimine, a silver-catalyzedelectrophiliccyclizationreaction of alkyne, and a tautomerism/isomerism/metal-H exchange cascade. The iodine-mediated
