Solvent-free Mechanochemical and Liquid-phase Reaction of [60]Fullerene with Ethyl 2-Diazopropionate
Solvent-free Mechanochemical and Liquid-phase Reaction of [60]Fullerene with Ethyl 2-Diazopropionate
摘要
The solvent-free mechanochemical reaction and the liquid-phase reaction of C60 with ethyl 2-diazopropionate prepared in situ or preformed from alanine ethyl ester hydrochloride and sodium nitrite have been investigated. Methanofullerene 1 and fulleroids 2 and 3 from these reactions were obtained, meanwhile the pyrazoline intermediate was not observed. Fulleroids 2 and 3 can be converted to methanofullerene 1 in refluxing toluene.
