19845-69-3, 1,6-Bis(diphenylphosphino)hexane is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: A mixture of the dimeric complex [Pd(mu-Cl)(Cl)(NHC)]2(0.10 mmol) and the appropriate diphosphine ligand (0.10 mmol) was dissolved in CH2Cl2 (5.0 mL) and stirred at ambient temperature overnight. The reaction mixture was filtered over Celite, the solvent was reduced under vacuum to about 1.0 mL and the yellow precipitate formed by careful addition of n-hexane (c.a. 10 mL). The yellow solid was then filtered off, washed with n-hexane, and dried under vacuum.

50777-76-9, General procedure: To a mixture of 2-(diphenylphosphino)benzaldehyde(500 mg, 1.72 mmol) and the appropriate amine(1.81 mmol) was added formic acid (1 drop) in MeOH(5 mL). The reaction was allowed to proceed at RT for18 h, at which point the iminophosphine pro-ligand was collected by suction filtration as a pale yellow precipitate. Spectroscopic NMR data were collected in CDCl3 as the pro-ligands decompose in wet DMSO-d6. The spectroscopically pure pro-ligands were used as prepared to make the corresponding platinum(II) complexes.
