title: Synthesis and structure of the first 1,2sigma5-selenaphosphirane.
abstract: A 1,2sigma5-selenaphosphirane bearing the Martin ligand was synthesized. Its structure in both the solid and the solution state was established by X-ray crystallographic analysis and NMR measurements, respectively. The selenaphosphirane has a polar P-Se bond, and the selenium atom is negatively charged. In the solution state, the degree of polarization of the P-Se bond depends on the acceptor number of the solvents.
