โฆ Synopsis
A_b initio calculations show borepin to be planar and more stable than its valence isomers boranorbornadiene and boranorcaradiene by a considerable amount; the latter have C, symmetry.
Borepin (I) is perhaps the most conspicuously monocyclic 4n+2 pi-electron systems. In contrast

Ab initio calculations show that the cyclic aromatic structure (hexaphosphabenzene) is a minimum on the Ps potential energy surface, and is kinetically stable to its unimolecular destruction. In contrast to the N, analogue, hexaphosphabenzene lies very close in energy to its valence Ps isomers. This
