Technology Process of heptadecacarbonyl(triphenylphosphine)hexaosmium⁽⁰⁾

There total 2 articles about heptadecacarbonyl(triphenylphosphine)hexaosmium⁽⁰⁾ 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:

octadecacarbonylhexaosmium (37216-50-5) → hexadecacarbonylbis(triphenylphosphine)hexaosmium(0) (101136-83-8) + heptadecacarbonyl(triphenylphosphine)hexaosmium(0) (101136-84-9)

Guidance literature:

With trimethylamine-N-oxide; triphenylphosphine; In dichloromethane; Addn. of excess PPh3 to Os6(CO)18 in CH2Cl2, cooling of mixt. to 195 K, and then dropwise addn. of Me3NO (CH2Cl2, dry N2) over 10 min with stirring.; React. mixt. is allowed to warm up slowly to room temp. with stirring, and then reduced in volume. Sepn. of resulting materials (including 5% of initial Os6(CO)18) by TLC (CH2Cl2/hexane), crystn. of Os6(CO)17PPh3 from CH2Cl2/hexane.;

Reference yield:

octadecacarbonylhexaosmium (37216-50-5) → heptadecacarbonyl(triphenylphosphine)hexaosmium(0) (101136-84-9)

Guidance literature:

With CH₃CN; (CH₃)3NO; triphenylphosphine; In dichloromethane; acetonitrile; 195 K; recrystd. (CH2Cl2);

Reference yield:

heptadecacarbonyl(triphenylphosphine)hexaosmium(0) (101136-84-9) → {dihydridohexaosmium(carbonyl)15(PPh2)C6H4}(PPN) + {hydridohexaosmium(carbonyl)16(PPh3)}(PPN)

Guidance literature:

With trimethylamine-N-oxide; In dichloromethane; Dropwise addn. of 2 equiv. of Me3NO (CH2Cl2) to CH2Cl2 soln. of Os-compd. under dry N2 over 5 min with stirring, results immediately in colour change from brown to red-brown.; Sepn. of PPN salts by TLC, eluting with CH2Cl2/hexane. Spect. identification of orange dihydrido-complex.;
