Technology Process of dicarbonylpentaphenylcyclopentadienylcobalt

There total 5 articles about dicarbonylpentaphenylcyclopentadienylcobalt 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: 81.0%

potassium tetracarbonylcobaltate (14878-26-3) + 1-bromo-1,2,3,4,5-pentaphenylcyclopenta-2,4-diene (56849-84-4) → dicarbonylpentaphenylcyclopentadienylcobalt (90502-88-8)

Guidance literature:

In tetrahydrofuran; stirred for 3 d at room temp.; chromy.;

Reference yield: 65.0%

dicobalt octacarbonyl (15226-74-1,61091-28-9,61117-58-6) + 1-bromo-1,2,3,4,5-pentaphenylcyclopenta-2,4-diene (56849-84-4) → dicarbonylpentaphenylcyclopentadienylcobalt (90502-88-8)

Guidance literature:

With zinc; In tetrahydrofuran; (dry N2); zinc dust (3.06 mmol) and Co2(CO)8 (1.46 mmol) added to soln.of C5Ph5Br (2.93 mmol); stirring (1 h); react. mechanism discussed; resulting soln. evapd. to dryness; extn. (CH2Cl2); chromy. (alumina, CH2Cl2/n-hexane 1/5); crystals obtained; elem. anal. and mass spectrum;

Reference yield: 56.0%

carbonyldi-iodo(η5-pentaphenylcyclopentadienyl)cobalt(III) (106223-27-2) + phosphorous acid trimethyl ester (121-45-9) → dicarbonylpentaphenylcyclopentadienylcobalt (90502-88-8) + Co(CO)(P(OCH3)3)(C5(C6H5)5)

Guidance literature:

With Co(C₅H₅)2; In toluene; byproducts: (Co(C5H5)2)I; (dry N2); to soln. of P(OCH3)3 (0.87 mmol) added CoI2(CO)(C5(C6H5)5 (0.41 mmol) followed by Co(C5H5)2 (0.87 mmol); (Co(C5H5)2)I ppt. filtered off (Celite); filtrate evapd.; extn. (CH2Cl2); chromy. (alumina, CH2Cl2/n-hexane): elution (1/5) gave small quantities of Co(CO)2(C5Ph5), further elution (1/3) gave Co(CO)(P(OCH3)3)(C5Ph5)(elem. anal.);
