Unequivocal assignment of the fullerene carbons of diethyl 1, 2-methano[60]fullerene 61, 61-dicarboxylate using 2D INADEQUATE NMR spectroscopy

摘要

Assignment of all carbons of the [60]fullerene sphere of diethyl 1, 2-methnano[60]fullerene 61, 61-dicarboxylate using 2D INADEQUATE NMR spectroscopy is described. Acquiring the INADEQUATE data with small spectral widths and optional F_1 folding with States-TPPI phase implementation provides a convenient route to high-resolution data. A description of the topology of the [60]fullerene sphere and its comparison with x-ray crystallographic analysis is also presented.
