DIAMINO AND TETRAAMINO DERIVATIVES OF BUCKMINSTERFULLERENE C-60

Mainly mono- and bisadducts are formed in the reaction of C60 with secondary diamines in toluene. The basic C60 derivatives can be obtained in pure form. Elemental analyses and NMR and mass spectra indicate that these monoadducts have the structure 1; thus. the addition of the diamine is apparently followed by a dehydrogenation R1, R2 are for example CH3.
