Technology Process of η6-stilbene chromium tricarbonyl

There total 17 articles about η6-stilbene chromium tricarbonyl 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: 72.0%

tricarbonyl(η(6)-toluene)chromium (12083-24-8) + stilbene (588-59-0) → η6-stilbene chromium tricarbonyl (12155-45-2,12155-44-1,1003605-45-5,32825-34-6) + (stilbene)bis(tricarbonylchromium) (83861-09-0,32823-69-1,83861-10-3)

Guidance literature:
