Abstract:
A method for preparing cis-di(thiocyanato)-N,N-bis(2,2-bipyridyl-4,4-dicarboxylic acid)ruthenium(II)(N3) is provided to improve the yield significantly and mass-produce an N3 dye industrially. A method for preparing cis-di(thiocyanato)-N,N-bis(2,2-bipyridyl-4,4-dicarboxylic acid)ruthenium(II) comprises a step of subjecting a ruthenium(III) chloride hydrate, 2,2'-bipyridin-4,4'-dicarboxylic acid and an alkali metal salt of thiocyanic acid to reflux reaction using dimethyl formamide(DMF) or an aqueous solution of the DMF as a solvent in a microwave reactor irradiating microwave having a wavelength of 355W. Further, 5 to 95 vol.% of dimethyl formamide is comprised in the aqueous solution of the DMF.
