Studies from University of Guilan in the Area of Molecular Catalysis Described (Application of cellulose/chitosan grafted nano-magnetites as efficient and recyclable catalysts for selective synthesis of 3-indolylindolin-2-ones)

By a News Reporter-Staff News Editor at Science Letter -- New research on Molecular Catalysis is the subject of a report. According to news reporting out of Rasht, Iran, by NewsRx editors, research stated, "Cellulose grafted to nano-magnetites was found to be an efficient biopolymer composite for catalysis of Friedel Crafts reaction between isatins and indoles, leading to selective synthesis of 3-hydroxy-3-indolylindolin-2-ones."

Our news journalists obtained a quote from the research from the University of Guilan, "The catalysis process is likely effected by a mass of hydroxyl groups arranged along the backbone of cellulose fibers coated on surface of the nano-sized magnetite support, where they get exposed to the adsorbed substrates. Synergistic push-pull effects, reminiscent of the soft catalysis of metal-less enzymes, via proton donating-accepting functions of the hydroxyl groups anchored on surface of the cellulose shell were invoked to explain the clean and selective bioorganocatalysis of 3-indolylindolin-2-one formation."

According to the news editors, the research concluded: "In addition, more improvement in this selective catalytic performance was realized by employing the magnetite nano-particles coated with chitosan shell."
