Diphosphines with strongly polarized P-P bonds: Hybrids between covalent molecules and donor-acceptor adducts with flexible molecular structures

Article abstract of DOI:10.1021/ja903156p

A series of P-phospholyl-substituted N-heterocyclic phosphines was prepared and characterized by single-crystal X-ray diffraction and solution and solid-state ³¹P NMR spectroscopy. The molecular structures are distinguished by the presence of P
