Complexation associated rearrangement of iminobiphosphines to diphosphinoamines

The reaction of the iminobiphosphines RN{double bond, long}PPh2-PPh2, where R = C6H4(p-CN), C6H4(m-CN), C6H4(o-C6H5), C6F5 or C6H4(o-CF3), with one molecular equivalent of M(cod)Cl2 (M = Pd or Pt) results in a rearrangement of the N{double bond, long}P{single bond}P unit to the more commonly encountered P-N-P unit, forming mono-chelating complexes of general formula M{RN(PPh2)2}Cl2. The related reaction of the same range of iminobiphosphines with Pt(cod)Cl2 (but not Pd(cod)Cl2) in 2:1 ratio affords complexes of general formula [Pt{RN(PPh2)2}2]2Cl. All 15 complexes are isolated in moderate to high yield and they have been fully characterised by spectroscopic methods. Six complexes, viz. [M{C6H4(p-CN)N(PPh2)2}Cl2], [M{C6H4(m-CN)N(PPh2)2}Cl2] and [M{C6H4(o-C6H5)N(PPh2)2}Cl2] (M = Pd and Pt), have been characterised in the solid state by single crystal X-ray diffraction analysis.

On the reactivity of the iminodiphosphane C6H 4(o-CN)N=PPh2-PPh2: Fragmentation versus isomerisation

The reactivity of the iminodiphosphane C6H4(o-CN)N= PPh2-PPh2, which contains an N=P-P unit, has been investigated. Reaction with small molecules, [viz. H2P/O2, H2O2,
