反应条件
potassium hydrogencarbonate in ethanol; water RuCl3 in EtOH and water was refluxed for 4-5 h. An excess amount of theligand was added to the blue soln. and the mixture was refluxed until its color turned red. After cooling KHCO3 was added in several portions, followed always by 1-3 h reflux.; concn., filtration, extn.(benzene),The extn. was chromd., evapn. ,recrystn. (EtOH);
