Notizen:
Three isomeric monoadducts 2aA, 2aB, and 2aC of fullerene-70 with 2,4,6-trimethoxybenzonitrile oxide 1a were synthesized and isolated. With a combination of FAB-MS, 13C- and 1H-NMR spectroscopy the structure of the orientational and regioisomers could be assigned. A precise X-ray structure analysis of the isomer 2aA with the substituent placed above the pole could be performed at low temperature (170 K). The corresponding monoadduct 3a of C60 was synthesized, isolated and characterized. In the same manner a mixture of three isomeric monoadducts 2b of C70 with ethoxycarbonylnitrile oxide 1b was obtained and characterized. The monadducts 2c of C70 with 9-anthrylnitrile oxide 1c were characterized by FAB-MS.
