Studies from PRESTO in the Area of Hydrogen Reported (Synthesis of Open-Cage Ketolactam Derivatives of Fullerene C-60 Encapsulating a Hydrogen Molecule)

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Hydrogen have been published. According to news originating from Saitama, Japan, by NewsRx correspondents, research stated, "A novel open-cage fullerene C-60 derivative having a bis(hemiketal) moiety was synthesized by the reaction of C-60-N-MEM-ketolactam (MEM: 2-methoxyethoxymethyl) with N-methylmorpholine N-oxide in the presence of water. The structure was clearly determined by single crystal X-ray analysis."

Our news journalists obtained a quote from the research from PRESTO, "Further enlargement of the opening was performed by treatment with trifluoroacetic anhydride to give the tetraketo derivative having a 15-membered ring opening. For H-2-insertion into the cage, the derivative was exposed to a high pressure of H-2. After the encapsulation, the opening size was reduced to the original one while keeping the hydrogen molecule inside the cage."

According to the news editors, the research concluded: "This compound can be a possible precursor for endohedral azafullerenes encapsulating a hydrogen molecule."
