The nucleophilic attack of N-methylimidazole at the bridge phosphorus of a 7-phosphanorbornadiene pentacarbonylmolybdenum complex induces the collapse of the bridge. According to DFT calculations, the resulting zwitterion displays a very long and weak P - Mo bond. The excess of, N-methylimidazole thus appears to be able to displace the phosphinidene from its molybdenum complex. The final result is a phosphinidene- N-methylimidazole adduct whose structure has also been computed. When applied to the phenyl derivative at 40°C in toluene, this reaction effectively generates the [PhP] adduct, which decomposes to give essentially Ph4P4 and Ph5P5. At 80°C, PhPH2 is also produced. In the presence of CCl4 the phosphinidene adduct inserts into the C-Cl bond to give PhP(Cl)CCl 3.
