S. Muthu et al., REACTION OF BUCKMINSTERFULLERENE WITH 1,3-DIPHENYLNITRILIMINE - SYNTHESIS OF PYRAZOLINE DERIVATIVES OF FULLERENE, Tetrahedron letters, 35(11), 1994, pp. 1763-1766
1,3-diphenylnitrilimine generated in situ undergoes 1,3-dipolar cycloa
ddition with C-60 to form a diadduct which is characterised by FAB mas
s spectrum and other spectroscopic techniques.
