Intramolecular coordination at phosphorus: donor-acceptor interaction in three- and four-coordinated phosphorus compounds

Article abstract of DOI:10.1016/0022-328X(95)00318-K

The phosphorus derivatives P(X)(O2C6H4-1,2)2 (9-11) undergo ready extension of coordination by N -> P intramolecular donor-acceptor interaction as shown by 31P NMR and dynamic 1H NMR spectroscopy.This extension of coordination does not o
