“…A preparation of new carbon based nano‐composite and its utility in one pot synthesis of hexahydroacridine‐1,8‐ diones was demonstrated by Kour and coworkers [115] . This reusable nanocomposite was prepared from the reaction of activated cellulose with previously reacted mercaptoethanol and chlorosulfonic acid, and obtained a blackish solid, cellulose[2‐(sulfooxy)ethyl]mercaptosulfonic acid[SEMSA] catalyst.…”

The unpretentious features of acridine‐1,8‐diones viz. presence of N‐heteroatom, electronic behavior, acridine ring skeleton and wide possibilities of diversified substitution, bichromophoric structure and interaction ability with various proteins, make them an interesting scaffold of heterocyclic, medicinal and industrial chemistry. A tremendous development in the field of acridinediones in terms of synthetic strategies, bioactivity, industrial and other applicability has been explored in past four decades. In this perspective, an overview has been given on the state‐of‐art discoveries for the synthesis and biological applications of acridine‐1,8‐diones from 1980 to 2020. The study highlighted the history, chemistry and properties of these derivatives and provided deep insights into the synthetic protocols using various catalysts and techniques like nano‐catalyst, ionic‐liquids, microwave, ultrasound etc. under varied conditions along with biological activity against many lethal diseases. Finally, the respective prospects and limitations to these systems have been addressed. Furthermore, attempts have been done to bring many outstanding researches together and express the significance of acridine‐1,8‐diones through several aspects. We hope that the article shall deliver an impetus to explore further the synthetic values and mechanistic puzzles of acridinedione moiety and to design more promising hybrid multi‐targeted drugs and other industrial composites for the goodness of humanity

“…One-pot method was also used to prepare carbon-based solid acid catalysts. Distillers' grain, [15] naphthalene, [16] glycerol, [17] 2methylnaphthalene [18] and activated cellulose [19] were simultaneously carbonized and sulfonated with concentrated sulfuric acid. The catalysts prepared by one-pot method have high sulfonic groups density (> 4 mmol g À 1 ), but the sulfoaromatic rings was carbonized in concentrated sulfuric acid at a temper-ature above 200°C, leading to a lot of problems in one-pot method in terms of safety and large-scale production.…”

Carbon-based solid acid catalysts were successfully prepared by hydrothermal carbonization method and one-pot method using naphthalene crosslinked by formaldehyde and sulfonated by H 2 SO 4 (98 %). The characterization results showed that the catalysts prepared by hydrothermal carbonization method had more amorphous carbon composed of aromatic carbon sheets with functional groups (À SO 3 H, À COOH and À OH) than the catalyst prepared by one-pot method. The preparation conditions of hydrothermal carbonization method were optimized.The FÀ NÀ SO 3 H-h-2.49 (1 : 11) prepared under optimal conditions showed high conversion of cyclohexane (48.2 %) and selectivity to nitrocyclohexan (98.2 %) at 125°C for liquid-phase nitrification, attributed to high acid site density (3.08 mmol/g) and amorphous carbon structure with hydrophilic functional groups. The FÀ NÀ SO 3 H-h-2.49 (1 : 11) also showed excellent thermal stability until 460°C. The thermal stability of the catalyst is due to mutual electron-withdrawal of aromatic carbon sheets.
