| Abstract: | Ammonium dialkyl phosphoroselenoates are directly converted into the dialkyl phosphoramidates by iodosobenzene and iodoxybenzene. The inversion of configuration at the phosphorus atom, using model diastereoisomeric ammonium cis‐ and trans‐2‐oxo‐2‐seleno‐4‐methyl‐1,3,2‐dioxaphosphinan system, was observed. The mechanistic scheme of this transformation is discussed. © 2003 Wiley Periodicals, Inc. Heteroatom Chem 14:121–127, 2003; Published online in Wiley InterScience (www.interscience.wiley.com).
