[12081-16-2] C8H16Cl2Rh2 (MW 388.93) InChI = 1S/4C2H2.2ClH.2Rh/c4*1-2;;;;/h4*1-2H;2*1H;; InChIKey = OYVJBXLXBKTBFO-UHFFFAOYSA-N (precatalyst for additions of organometallic reagents to π-bonds, cycloadditions, and cycloisomerizations) Alternate Names: bis(ethylene)rhodium(I) chloride dimer and di-μ-chlorotetraethylene dirhodium(I). Physical Data: decomposes before melting. Solubility: sparingly soluble in ethanol, acetone, dioxane, chloroform, and dichloromethane; insoluble in water. Form Supplied in: red orange powder; commercially available from Strem, TCI, Sigma-Aldrich, and so on. Analysis of Reagent Purity: by IR spectroscopy.1 Preparative Methods: prepared by stirring a solution of RhCl3(3H2O in aqueous methanol under an atmosphere of ethylene at room temperature. The product begins to precipitate after 1 h and the red-orange solid is collected after 7 h by filtration and washed with methanol.1 Handling, Storage, and Precautions: air sensitive; should be stored under an inert atmosphere at −20 °C.
