The first greenest methodology for the synthesis of 2,3-dihydro-1H-perimidines on water is described. 1,8-Diamino naphthalene was reacted with different types of aldehydes at room temperature to furnish the product in moderate to excellent yields in 30 min. A multi-gram scale reaction is also performed to ensure the scalability of the reaction.

A rapid, efficient, and green grinding assisted method for the synthesis of 2,3‐dihydro‐1H‐perimidines has been developed. 1,8‐Diaminonaphthalene and aldehydes were ground using mortar and pestle for 5 minutes affording the product in moderate to excellent yields. The methodology minimises the use of conventional workup and column chromatographic techniques.

(Triazinediyl)bis sulfamic acid-functionalized silica-coated magnetite nanoparticles have been prepared and applicated as an efficient catalyst for synthesis of mono-, bis-, tris- and spiro-perimidines. The desired products have been synthesized in high purity and good yields. The workup procedure of reaction is simple. The catalyst was easily separated from the reaction mixture with the assistance
Synthesis of new TCH/Ni‐based nanocomposite supported on SBA‐15 and its catalytic application for preparation of benzimidazole and perimidine derivatives
microscopy, atomic absorption spectroscopy and N2 adsorption–desorption (Brunauer–Emmett–Teller) techniques. The catalytic performance of Ni/TCH@SBA‐15 (NNTS‐15) was determined for the synthesis of 2‐aryl‐substituted benzimidazoles and 2,3‐dihydroperimidines. The excellent yields within shorter reaction times, simplicity of catalytic methods, non‐toxicity and clean reactions, mild reaction conditions and easy

chlorosulfonic acid with zeolite-NaY undersolvent-freeconditions, which was then supported by Fe3O4 nanoparticles to give SO3H@zeolite-Y (Fe3O4/SO3H@zeolite-Y) magnetic nanoparticles. Several techniques were used to evaluate the physical and chemical characterizations of the zeolitic nanostructures. Fe3O4-loaded sulfonated zeolite was applied as a novel multi-functional zeolite catalyst for the synthesis of
