BoPhoz Ligands: Anodic Electrochemistry and Complexes^†

The oxidative electrochemistries of two chiral metallocene phosphine-aminophosphine (BoPhoz) ligands, R-Methyl BoPhoz ((R)-N-diphenylphosphino-N-methyl-[(S)-2-(diphenylphosphino)ferrocenyl]ethylamine) and R-Pcyco BoPhoz ((R)-N-dicyclohexylphosphino-N-methyl-[(S)-2-(diphenylphosphino)ferrocenyl]ethylamine)), were examined in methylene chloride. In addition the platinum(II) and palladium(II) complexes with a general formula [MCl2(P−P)] (M = Pd or Pt; P−P = R-Methyl BoPhoz or R-Pcyco BoPhoz) were prepared and characterized by NMR and cyclic voltammetry; the X-ray structures of the palladium complexes are reported.
