Solubility: CH2Cl2, toluene, benzene, 1,1,2-trichloroethane (TCE), 1,2-dichloroethane (DCE), methanol, water. Form Supplied in: light purple powder; commercially available (Strem, Aldrich). Preparative Methods: there are a number of reported routes for the preparation of 1. The reagent can be prepared from RuCl2 (PPh3)3 and diazoalkenes (e.g. N2CHPh),2 from Ru(cod)(cot) and gem-dihalides (PhCHCl2)3 or from RuCl3.4 Purification: usually the reagent is precipitated by addition of methanol. Additional washing with acetone and methanol is carried out prior to drying under vacuum. Handling, Storage, and Precautions: the reagent is air sensitive.
