Technology Process of chromium hexacarbonyl

There total 303 articles about chromium hexacarbonyl 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: 96.0%

(CO)5CrC(OEt)SiPh3 → chromium(0) hexacarbonyl (199620-14-9,13007-92-6) + triphenylhydroxysilane (791-31-1)

Guidance literature:

With carbon monoxide; In diethyl ether; High Pressure; under dried N2; addn. of N-methylbenzimine at 25°C to a soln. of W-complex (CO-pressure: 50 atm); stirring for 2 d at room temp., then for 1-2 h at 80-100°C; vac.-evapn. until dryness; residue dissolved in petroleum ether/ether; chromy. (silica gel/petroleum ether/ether); recrystn. from petroleum ether; elem. anal.;
