(Bis(diphenylphosphino)ethane)dichloronickel Use and Manufacturing

Methods of Manufacturing

[1, 2]-bis(diphenylphosphino)ethane nickel(II) chloride was obtained analogously to known procedure.15 The mixture of commercial NiCl2·2H2O (13.2 g, 0.08 mol) in 40 mL H2O with acetic acid (140 mL) was added to warm solution of 1, 2-bis(diphenylphosphino)ethane (31.8 g, 0.08 mol) in acetic acid (570 mL) with stirring. Reaction mixture was allowed to stay for ten hours. Pink-brown crystals were filtered, washed with cold acetic acid and dried in vacuum. Yield: 40.1 g (95percent). Suspension of di-thallium-3, 6-di-tert-butyl-catecholate prepared from o−quinone (0.044 g, 0.2 mmol) as it is described below in THF (10 mL), was added to [1, 2-bis(diphenylphosphino)ethane]nickel(II) chloride (0.1 g, 0.2 mmol) in THF (40 mL) in evacuated ampoule. Reaction mixture was refluxed for one hour. Solvent was changed to the mixture toluene/CH2Cl2 (~10/1, 50 mL), the mixture was filtered; solution volume was reduced to one half. Dark green solid, formed after cooling, was filtered, washed with light petroleum and dried in vacuum.
