Structure and solution behaviour of cyclooctadiene complexes of platinum(II)
Otto, Stefanus

The substitution behaviour of [PtCl(R)(COD)] (R- = Me and Fc) complexes, by the stepwise addition of phosphine ligands, L (L = PPh 3, PEt3 and P(NMe2)3), were investigated in situ by 1H and
Probing the bonding of phosphines and phosphites to platinum by NMR. Correlations of 1J(PtP) and Hammett substituent constants for phosphites and phosphines coordinated to platinum(II) and platinum(0)

The values of 1J(PtP) have been measured for the platinum(II) complexes cis-[PtCl2L2] and cis-[PtMeClL2] and the platinum(0) complexes [PtL(norbornene)2] and [PtL2(norbornene)] where L = P(C6H4Z-4)3 and [PtL2(norbornene)], [PtL3] and [PtL4] where L = P(OC6H4Z-4)3 and Z = NMe2, OMe, Me, H, Cl, CF3. When 1J(PtP) is plotted against the Hammett substituent constant two distinct trends emerge: for platinum(II) the more electron-withdrawing the substituent the smaller the 1J(PtP), while for platinum(0) the more electron-withdrawing the substituent the larger the 1J(PtP). These observations are rationalised in terms of the σ and π-bonding components of the platinum-phosphorus bonds.
