Technology Process of {Co4(CO)9(μ4-PPh)2C(O)H}Li

There total 1 articles about {Co4(CO)9(μ4-PPh)2C(O)H}Li 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:

Co4(CO)10(μ4-PPh)2 (58092-22-1) + lithium triethylborohydride (22560-16-3) → {Co4(CO)9(μ4-PPh)2C(O)H}Li (106733-92-0)

Guidance literature:

In tetrahydrofuran; THF soln. of LiEt3BH was added to the soln. of Co-cluster at -78°C under Ar atmosphere; not isolated; IR, (31)P, (13)C, and (1)H NMR spectral identification;

Reference yield: 80.0%

iron pentacarbonyl (13463-40-6,37220-42-1) + {Co4(CO)9(μ4-PPh)2C(O)H}Li (106733-92-0) → {Fe(CO)4CHO}(1-)*Li(1+)={Fe(CO)4CHO}Li + Co4(CO)10(μ4-PPh)2 (58092-22-1)

Guidance literature:

In tetrahydrofuran; equimolar amount of Fe(CO)5 was added to a THF soln. of Co-cluster at -60°C under Ar, mixt. was allowed to warm gradually to room temp.; Fe-complex was identified in reaction mixt. by IR and (1)H NMR spectroscopy (yield ca. 60%), Co-cluster was isolated by chromy. over SiO2 (eluant hexane);

Reference yield: 62.0%

{Co4(CO)9(μ4-PPh)2C(O)H}Li (106733-92-0) + trifluoroacetic anhydride (407-25-0) → Co4(CO)9(μ4-PPh)2{μ-C(O2CCF3)H} (106733-97-5)

Guidance literature:

In tetrahydrofuran; (CF3CO)2O was added to a THF soln. of the Co-cluster at -78°C under Ar, reaction was stirred with warming overnight; evapd., residue extd. with hexane; attempts to purify the cluster by column chromy. led to decompn.;
