Abstract
Abstract The reactions of [60]fullerene and amino acids in the absence of aldehyde in o-dichlorobenzene (ODCB) at 150 °C have been investigated. Fulleropyrrolidines 1 [C60(CH2N(CH3)CHC6H2(NO2)3)], 2 [C60(CH2N(CH3)CH2)], 3 [C60(CH2NHCH2)], and 5a–b [C60(RCHNHCHR), R˭CH3 (5a), R˭CH2Ph (5b)] were obtained in moderate yields from the reactions of C60 and corresponding amino acids. The reaction of C70 and N-methylglycine in the absence of aldehyde was also studied and was found to give the positional isomers of N-methyl[70]fulleropyrrolidines 6 (1,9-isomer) and 7(7,8-isomer). All products were fully characterized by ultraviolet–visible, Fourier transform–infrared (FT-IR), NMR, and mass spectrometry. The reactions were also carried out in the dark to exclude the possible interference of the photoinduced reactions, and almost the same yields of products were obtained.
