WebJul 5, 2024 · d-d π bonding occurs when an element such phosphorus, which has a σ-symmetry lone pair and an empty metal 3d orbital, binds to a metal that has electrons in a t 2g orbital. This is a common situation for phosphine complexes (e.g., triphenylphosphine) bound to low-valent, late transition metals. WebThe product phosphine is produced through reductive elimination of a P-C bond rather than a P-H bond in Glueck's system. [12] [13] The Ni (0) catalyst involves oxidation addition of a P-H bond to the metal, followed by insertion of the alkene into the M-H bond.
