The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 88.0%

[(1,2-bis(dicyclohexylphosphino)ethane)dichloronickel(II)] (96555-88-3) + ethene (74-85-1) → Ni(η(2)-C2H4)(1,2-bis(dicyclohexylphosphino)ethane) (91513-98-3)

Guidance literature:

With lithium; In tetrahydrofuran; C2H4 was bubbled through mixt. of Ni-complex, Li dispersion and THF under vigorous stirring until no more C2H4 was absorbed (2-3 h); evapn. to dryness, washed with ether, extd. with hot toluene, ext. filtered, concd., EtOH was added, resulting slurry was set aside at 0°C, filtered, ppt. was washed with EtOH, dried in vacuo;

Reference yield: 85.0%

[(bis(dicyclohexylphosphino)ethane)nickel(propanoate-3-yl)] → Ni(η(2)-C2H4)(1,2-bis(dicyclohexylphosphino)ethane) (91513-98-3)

Guidance literature:

In toluene; byproducts: CO2; a suspn. of Ni-complex in toluene was heated under ethylene atmosphere (1 bar) for 48 h at 60°C; filtered, filtrate was evapd. to dryness to give (diphosphine)Ni(C2H4);identified by IR spectrum;
