Treatment of (cod = cycloocta-1,5-diene) with the diphosphine (Ph2PCH2)2C=CH2 gives the complexes > (X=Cl 1a or Me 1c).The dichloro complex can be converted to give the corresponding diiodo complex by metathesis and isomerised by base (NaOH-EtOH) to give 2a.Treatment of complexes 1a, 1c or 2a with LiMe gives >- 3, containing a symmetrical anionic diphosphine, which reacts with MeOH to give 2b.Treatment of 1a or 2a with equimolar amounts of Cl2 produces the correponding tetrachloroplatinum(IV) complexes 4 and 5, whilst treatment of 1c with MeI gives > 6; 4-6 are all unstable in solution with respect to reductive elimination reactions, 4 and 5 giving 1a and 2a respectively whilst 6 gives >.Treatment of 3 with electrophilic reagents such as MeI, PCH2Br, SiMe3Cl or PPh2Cl gives complexes (R=Me 7a, PhCH2 7b, SiMe3 7c or PPh2 7d).Treatment of the salt 2>Cl2 9 with NaBH4 gives the platinum(0) compound 2> 9, whilst with LiBu-Me2NCH2CH2NMe2 it gives the unusual platinum(II) complex 10, in which the Pt is bonded to two P and two C atoms and two of the phosphorus atoms are uncomplexed.
