Abstract:
The quasi ab-initio PRDDO method, with and without the generalized valence bond (GVB)-type correlation of one pair of orbitals is used to examine some interesting features of the bonding in [1.1.1] propellane. It is found that the singlet, partial diradical configuration is the most stable one and that the central, interbridgehead bond is a weak one, i.e., it is characterized by a low degree of bonding. We thus integrate apparently contradictory evidence from former calculations. We also used the PRDDO approximation together with the synchronous transit method to study the rearrangement of [1.1.1]propellane to 3-methylene-cyclobutene, in theoretical detail. © 1986.
