Rhodium trichloride and its various hydrates can be considered the default halides of rhodium. By contrast, its lighter congener cobalt does not form a stable trichloride, mainly being available as cobalt(II) chloride. Anhydrous rhodium chloride is a dense red-brown solid.
It is a yellow, water-soluble solid. The salt is an intermediate in the purification of rhodium from its ores. As shown by X-ray crystallography, the salt consists of the octahedral complex [RhCl(NH 3) 5] 2+ and two chloride counterions. [1] It forms from the reaction of rhodium trichloride and ammonia in ethanol. [2]
The migratory insertion of this 18-electron complex can result in either a primary or secondary rhodium alkyl. This step sets the regiochemistry of the product, however it is rapidly reversible. This step sets the regiochemistry of the product, however it is rapidly reversible.
Organorhodium chemistry is the chemistry of organometallic compounds containing a rhodium-carbon chemical bond, and the study of rhodium and rhodium compounds as catalysts in organic reactions. [ 1 ] Stable organorhodium compounds and transient organorhodium intermediates are used as catalyst such as in olefin hydroformylation , olefin ...

Rhodium carbonyl chloride is an organorhodium compound with the formula Rh 2 Cl 2 (CO) 4. It is a red-brown volatile solid that is soluble in nonpolar organic solvents. It is a precursor to other rhodium carbonyl complexes, some of which are useful in homogeneous catalysis.
The compound is prepared by the reaction of rhodium trichloride trihydrate and pentamethylcyclopentadiene in hot methanol, from which the product precipitates: [1] 2 C 5 (CH 3) 5 H + 2 RhCl 3 (H 2 O) 3 → [(C 5 (CH 3) 5)RhCl 2] 2 + 2 HCl + 6 H 2 O. It was first prepared by the reaction of hydrated rhodium trichloride with hexamethyl Dewar ...
