Abstract

The effects of introducing nitrogen atoms in the fjord regions and chalcogen bridges on the conformations of overcrowded bistricyclic aromatic enes were studied. The structures were studied by ¹H, ¹³C, ⁷⁷Se and ¹²⁵Te NMR spectroscopy. It was found that the degrees of overcrowding in the fjord regions were relatively small.
