Unsymmetrical bidentate ligands bearing chiral phosphetane units
Marinetti,Kruger,Couetoux
, p. 1539 - 1543 (1998)
Bidentate ligands containing a PPh2 group and a P-chiral phosphetane moiety have been prepared from the optically pure P-menthyl substituted phosphetane oxide 4. The PPh2 group is introduced at a distance of three, four or five bonds from the other phosphorus atom by methodologies involving the corresponding hydroxy-substituted phosphetanes.
