1,10‐Phenanthrolin‐1‐ium Trinitromethanide (1,10‐PHTNM) as a Nano Molten Salt Catalyst With Y‐Aromatic Counter Ion: Applications for Synthesis of Organic Compounds

Abstract

Abstract1,10‐Phenanthrolin‐1‐ium trinitromethanide (1,10‐PHTNM) as a novel nano molten slat with Y‐aromatic counter ion was synthesized and fully characterized by using various techniques such as FT‐IR, 1H NMR, 13C NMR, mass, TGA, DTG, XRD, SEM and TEM. A series of organic compounds include 1,4‐dihydropyrano[2,3‐c]pyrazoles, tetrahydrobenzo[b]pyran, pyrano[4,3‐b]pyrans, bispyrazole, 1H‐pyrazolo[3,4‐b]quinolones, hexahydroacridine‐1,8‐diones and methylenebis(3‐hydroxy‐5,5‐dimethylcyclohex‐2‐enones) were synthesized in the presence of 1,10‐PHTNM as a novel and efficient proton sponge nano molten slat catalyst. According to the results of FT‐IR, 1H NMR, 13C NMR, mass spectrum of 1,10‐PHTNM and due to high electron charge density and none bonded repulsion of lone pair electrons between two nitrogen atoms (peri‐effect), this catalyst is a type of proton sponge.
