Technology Process of tetracarbonylbis(acetonitrile)tungsten

There total 4 articles about tetracarbonylbis(acetonitrile)tungsten 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: 83.0%

tungsten hexacarbonyl (14040-11-0) + acetonitrile (75-05-8,26809-02-9) → tetracarbonylbis(acetonitrile)tungsten (29890-10-6,16800-45-6,53447-66-8)

Guidance literature:

With trimethylamine-N-oxide; at 20 ℃; for 1.5h; Inert atmosphere;

DOI:10.1021/acs.inorgchem.8b00067

Reference yield: 65.0%

pentacarbonyl(diphenylcarben)wolfram + acetonitrile (75-05-8,26809-02-9) → cis-W(CO)4(acetonitrile)2 (16800-45-6,29890-10-6,53447-66-8) + pentacarbonyl(acetonitrile)tungsten (15096-68-1) + pentacarbonyl{diphenylmethyleneamino(methyl)carbene}tungsten

Guidance literature:

In acetonitrile; byproducts: diphenylketene; stirring at 50°C for 30 min (N2); evapn., chromy. (Kieselgel, -20°C) yields first (pentane/CH2Cl2) dinitrile complex (evapn., recrystn. (pentane/CH2Cl2)), then (CH2Cl2) nitrile complex (evapn., -20°C, high vac., elem. anal.); carbene complex and Ph2CCO are detected by IR;

DOI:10.1016/0022-328X(87)80228-0
