Pyridine analogue of macrocyclic polyyne C58H4N2 as a precursor to diazafullerene C58N2
Abstract
(1,3,5)Pyridinophanes having [4.3.2]propellatriene units were synthesized as precursors to macrocyclic polyyne C58H4N2; diazafullerene anion C58N2– was detected in the laser desorption mass spectrum of the pyridinophanes.
