Axial Preference of 2-Dithianyldiphenylphosphine Oxide. A Strong S-C-P Anomeric Interaction

Article abstract of DOI:10.1021/jo00146a048

Spectroscopic evidence indicates a predominantly axial conformation of 2-<1,3>dithianyldiphenylphosphine oxide.X-ray diffraction data confirm the axial orientation of the diphenylphosphinoyl substituent and, therefore, the existence of a strong S-C-P anom
