Notes:
P(III) double bond systems possess two closely spaced frontier orbitals, a π-orbital and a σ-orbital. In the parent iminophosphane the orbital sequence is σ (HOMO) and π* (LUMO). Thus, it is isolabal to a singlet carbene and undergoes self-dimerization via a [2 + 1] cycloaddition. The resulting three membered ring system can be considered as a complex of two iminophosphanes. Contrary to the classical cyclopropanation reaction, in the pseudo-carbene iminophosphane the corresponding [2 + 1] reaction is only slightly exothermic, as established by ab initio calculations at the SCF/CEPA-1 and the MCSCF/ACPF level.
