4,4 -Bipyridine, reaction with ruthenium chloro

The complex ion [Ru(bpy)(trpy)Cl] was first prepared as the perchlorate salt by the reaction of Ru(bpy)Cl4 with trpy in 25% aqueous ethanol, and more recently in 75% aqueous ethanol. It has also been prepared from Ru(CO)2(bpy)Cl2, trpy, and trimethylamine oxide in 2-methoxyethanol. A method in which the readily prepared RuftrpylClj complex is used as an intermediate is more convenient, and it is this new method that is described here. (2,2 -Bipyridine-A(,A( )chloro(2,2 6, 2"-terpyridine-Al,Al, N")osmium(II) chloride has been reported and is prepared from Os(bpy)Cl4" and trpy in ethylene glycol. (2,2 -Bipyridine-N,Al )chloro 2,2 6, 2"-terpyridine-Al,N, yV")osmium(II) chloride may also be prepared by the reaction of Os(trpy)Cl3 with bpy in ethylene glycol. However, the insolubility of Os(trpy)Cl3 in this solvent makes the procedure used for the ruthenium analog less desirable, and the literature method has been used without major modification. Reaction of the chloro complexes With hot... [Pg.299]
