A new chiral metalladiphosphine for early-late chemistry. Crystal structure of a D-camphor-based zirconium enolato phosphine and rearrangement of heterobimetallic Zr/Pd complexes

The bis(phosphinoenolato) zirconocene 2, prepared from the phosphino camphor derivative 3-exo-PPh2C10H15O 1, represents the first C2-symmetric chiral diphosphine containing an early transition metal centre tethered to the phosphino groups via an enolato linkage. It allows the selective assembly of Lewis-acid early-late bimetallic combinations, as exemplified with the Zr/Cu and Zr/Ag complexes 4 and 5. The monophosphinoenolato titanocene 3 was also prepared. Reactions of 2 or 3 with [Pd(dmba)(μ-Cl)]2 (dmba = o-C6H4CH 2NMe2) or [PdCl2(SEt2)2] led to complete transfer of the functional ligand to the Pd(II) centre, with formation of [(dmba)Pd(PPh2C10H14O)] 6 or cis-[Pd(PPh2C10H14O)2] 8 and [Cp2ZrCl2]/[Cp2TiCl2], respectively. A heterobimetallic Zr/Pd intermediate complex 10 of this rearrangement could be detected. Complexes 6 and 8 were prepared independently by reaction of 1 with [Pd(dmba)(μ-Cl)]2 or [Pd(SEt2)2Cl 2], respectively, which first afforded complexes 7 and 9 which were then treated with KH. The crystal structures of 2, 6 and 8·THF· H2O have been determined by X-ray diffraction. The Royal Society of Chemistry 2001.

Camphor-derived β-Ketophosphine Complexes of Palladium(II) and Platinum(II)

Reaction of chlorodiphenylphosphine with the lithium enolate derived from the treatment of (1R)-endo-(+)-3-bromocamphor (camphor = bornan-2-one) with n-butyl-lithium gives (1R)-endo-(+)-3-diphenylphosphinocamphor (L).This new chiral β-ketophosphine ligand reacts with to give trans-, and in a 1:1 ratio to give the chloro-bridged dimer 2>.The ligand L reacts with to give trans-.Thermolysis of (M = Pd or Pt) in refluxing xylene gives mixed phosphine-phosphinite complexes with mutually cis chlorides.The complex reacts with an excess of AgBF4 to give 2 which is shown to contain bidentate binding through the phosphorus and keto-oxygen atoms.All complexes are characterised by i.r., 1H and 31P n.m.r. spectroscopy.
