P-Chiral Phosphinoselenoic Chlorides and Optically Active P-Chiral Phosphinoselenoic Amides: Synthesis and Stereospecific Interconversion with Extrusion and Addition Reactions of the Selenium Atom

An efficient synthesis of P-chiral phosphinoselenoic chlorides and the first optically active P-chiral phosphinoselenoic amides was successfully achieved. Stereospecific interconversion with the extrusion of selenium atom from optically active phosphinoselenoic amides and the addition of selenium atom to optically active aminophosphines were also investigated.
