Phosphine Alkylenes, 50. - On the Structure of 2,2,2-Triphenyl-1,2-λ5-oxaphospholanes

2,2,2-Triphenyl-1,2-λ5-oxaphospholanes (5a-h) were synthesized from methylene-triphenylphosphorane (1, R=H) and suitable epoxides (2a-g).Oxaphospholane 5e was subjected to an X-ray structural analysis, which showed a five-membered ring-structure with a trigonal-bipyramidal coordinate phosphorus atom.One phenyl group and the ring oxygen atom are apical ligands at phosphorus.According to the NMR spectra, oxaphospholanes have a ring structure in nonpolar solvents, whereas in polar solvents there exists an equilibrium with an open-chain form.Key Words: Phosphorus, tetra- and pentacoordinate / Oxaphospholanes / Trigonal-bipyramidal structure / Eqquilibrium of ring and betain structure in polar solvent
