WebJun 10, 2016 · For both phosphine and ammona, there is a backbonding n M σ N / P ∗ interaction. These ligands can act as π-acceptors in much the same way as C O, except that they have unoccupied σ* orbitals rather than π* orbitals. N H X 3 is, however, a weaker π-acceptor than P H X 3, but it is still a fairly high field-ligand. WebA phosphine ligand is a type of ligand containing a P atom in an atom, a molecule or an ion, which is bonded to a central atom (metal or metalloid). The simplest phosphine ligand is triphenylphosphine. The synthesis of phosphine ligands began as early as the 1860s, and the initial phosphine ligands were mainly used for chiral catalysis in the ...
