Chloro(1,3-dimesityl-1H-imidazol-2(3H)-ylidene)aurate(I) is a reagent used in organic syntheses. It is soluble in many organic solvents and reacts as an active catalyst with silver chloride. Chloro(1,3-dimesityl-1H-imidazol-2(3H)-ylidene)aurate can be prepared by reacting equimolar amounts of chloroauric acid with an excess of the desired carbene in a solvent. The reaction is typically carried out at room temperature or at reflux. Preparative methods for this compound include the use of chlorobenzene as a solvent and heating to reflux. Chloro(1,3-dimesityl-1H-imidazol-2(3H)-ylidene)aurate is also soluble in ether and dieth
