A novel reaction: [60,70]fullerene reacting with 4,4,5,5-tetramethylimidazoline-2-thione and α-aminoacids as carbene reaction Original Research Article

The results of characterization had shown that it was [1+2] cycloaddition reaction when [60,70]fullerene reacted with 4,4,5,5-tetramethylidazoline-2-thione (1) and dl-valine by FT-IR, FD-mass, 1H NMR, 13C NMR, UV–Vis spectra. [60]fullerene reacting with 4,4,5,5-tetramethylidazoline-2-thione (1) and other α-aminoacids such as l-leucine and α-aminoisobutyric acid had been also done in order to understand the reaction better, and the possible mechanism was put forward based on the results of characterization. In this reaction, reaction temperature was very important due to the reactivity of different α-aminoacids and the result of the experiment had also shown that the reactivity of dl-valine was more reactive than that of other two α-aminoacids.
