Synthesis and characterisation of monophosphines and aminophosphines bearing chiral phosphetane units

Enantiomerically pure monophosphines beating: phosphetane units have been p repared from primary phosphines and the cyclic sulfates of anti-1,3-diols, Various substituents have been introduced on both the phosphorus and the ri ng carbon atoms, thus showing the high flexibility of the synthetic approac h. The same synthetic method has been applied to the preparation of P-N het erobidentate ligands bearing phosphetane and azetidine rings. The final pro ducts have been characterised by X-ray diffraction studies.
