Rhodium (Ⅲ) Chloride Hydrate is a catalyst for conjugate reduction of cinnamaldehydes followed by cross-coupling with arylboronic acids. Molecular weight 209.26. It is a catalyst for the direct conversion of methane to acetic acid. Rhodium(III) chloride refers to inorganic compounds with the formula RhCl3(H2O)n, where n varies from 0 to 3. These are diamagnetic solids featuring octahedral Rh(III) centres. Molecular formula, RhCl3?3H2O. Depending on the value of n, the material is either a dense brown solid or a soluble reddish salt. The soluble salt is widely used to prepare compounds used in homogeneous catalysis.
Rhodium (Ⅲ) Chloride Hydrate is an important chemical catalyst, used in purifying tail gas and pharmaceutical industry. It occurs as a red brown crystalline powder, easily soluble in water, hydrochloric acid, alcohol and alkali solution, insoluble in aether or aqua regia. The relative distribution of these species determines the colour of the solutions, which can range from yellow (the hexaaquo ion) to "raspberry-red." This and many related discoveries nurtured the then young field of homogeneous catalysis, wherein the catalysts are dissolved in the medium with the substrate. Previous to this era, most metal catalysts were "heterogeneous", i.e. the catalysts were solids and the substrates were either liquid or gases.
