Technology Process of Rhodium

There total 293 articles about Rhodium 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: 77.8%

di-μ-chloro-bis(1,5-cyclooctadiene)dirhodium (12092-47-6) → {rhodium(1,5-cyclooctadiene)H}4 + rhodium (378784-00-0,7440-16-6)

Guidance literature:

With lithium triethylborohydride; In tetrahydrofuran; slow addn. of THF soln. of LiB(C2H5)3H to soln. of Rh complex in THF cooled in ice bath, under dry N2; stirring at room temp. for 16 h;; removal of volatile components in vac.; extraction of residue with pentane; pentane extractant yields (RhH(C8H12))4; washing residue with THF; centrifugation yields Rh; heating in vac. at 400°C for 2 h; TEM; electron and X-ray diffraction;;
