Abstract
The mode of electron delocalization of novel polycyclic dianions, viz. acephenanthrylene dianion (22-) and aceanthrylene dianion (32-), is deduced from their* H and 13C NMR parameters (1D and 2D NMR). While the reduction of acephenanthrylene (2) afforded only the respective dianion (22-), the reduction of aceanthrylene (3) afforded dianion (32-) followed by monoanion (4). The electron delocalization of the neutral systems (2, 3) as ...
