Technology Process of CID 12856621

There total 10 articles about CID 12856621 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:

chromium(0) hexacarbonyl (199620-14-9,13007-92-6) → chromium tetracarbonyl (56110-59-9)

Guidance literature:

In neat (no solvent); byproducts: CO; Irradiation (UV/VIS); photolysis of Cr(CO)6 (0.02 Torr) in presence of He (80 Torr) and CO (0.400 Torr) in Pyrex cell using KrF-laser (248 nm); product formation detected by time-resolved IR-spectroscopy;

DOI:10.1021/ja00215a014

Reference yield:

chromium(0) hexacarbonyl (199620-14-9,13007-92-6) → chromium tetracarbonyl (56110-59-9) + pentacarbonylchromium(0) (26319-33-5,42386-76-5,54822-35-4)

Guidance literature:

In gas; byproducts: CO; Irradiation (UV/VIS); Cr complex irradiated at 300 K with KrF* laser; not isolated, detected by UV; Kinetics;

DOI:10.1021/ja00358a053
