Jh. Xu et al., A novel reaction: [60,70]fullerene reacting with 4,4,5,5-tetramethylimidazoline-2-thione and alpha-aminoacids as carbene reaction, J PHYS CH S, 61(7), 2000, pp. 1081-1088
The results of characterization had shown that it was [1 + 2] cycloaddition
reaction when [60,70]fullerene reacted with 4,4,5,5-terramethylidazoline-2
-thione (1) and DL-valine by FT-IR, FD-mass, H-1 NMR, C-13 NMR, W-Vis spect
ra. [60] fullerene reacting with 4,4,5,5-tetramethylidazoline-2-thione (1)
and other alpha-aminoacids such as L-leucine and alpha-aminoisobutyric acid
had been also done in order to understand the reaction better, and the pos
sible mechanism was put forward based on the results of characterization. I
n this reaction, reaction temperature was very important due to the reactiv
ity of different ol-aminoacids and the result of the experiment had also sh
own that the reactivity of Dr-valine was more reactive than that of other t
wo alpha-aminoacids. (C) 2000 Elsevier Science Ltd. All rights reserved.
