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.
