Technology Process of {(cobalt)2(carbonyl)4(μ-dppm)2}

There total 4 articles about {(cobalt)2(carbonyl)4(μ-dppm)2} which guide to synthetic route it. 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:

{(cobalt)2(carbonyl)2(μ-carbonyl)2(μ-dppm)2} → {(cobalt)2(carbonyl)4(μ-dppm)2} (56172-96-4,115558-02-6)

Guidance literature:

In dichloromethane;

DOI:10.1016/S0020-1693(00)81558-3

Reference yield:

cobalt(II) bromide hexahydrate + bis-diphenylphosphinomethane (2071-20-7) → {(cobalt)2(carbonyl)4(μ-dppm)2} (56172-96-4,115558-02-6) + {(CO)2(η1-bis(diphenylphosphino)methane)Co(μ-bis(diphenylphosphino)methane)BH2}*0.5CH2Cl2

Guidance literature:

With CO; NaBH₄; In ethanol; benzene; EtOH soln. of NaBH4 was added to CO satd. soln. of CoBr2*6H2O and phosphine deriv. in EtOH/C6H6 soln. over 30 min, mixt. was stirred for 4 h; solvents were removed, residue washed with EtOH and recrystd. from CH2Cl2/EtOH; large yellow crystals were sepd. by hand from black (CO)4Co(PPh2CH2Ph2)2;

Reference yield:

cobalt(II) chloride hexahydrate + carbon monoxide (201230-82-2) + bis-diphenylphosphinomethane (2071-20-7) → {(cobalt)2(carbonyl)4(μ-dppm)2} (56172-96-4,115558-02-6) + Co2(μ-H)(μ-PPh2)(μ-bis(diphenylphosphino)methane)2(CO)2

Guidance literature:
