Ag+-free complexation of alkyne-bipyridines at ruthenium(II) polypyridine centers proceeds with surprisingly low yields. The alkyne-bipyridine-substituted ruthenium(II) polypyridine complexes in this work were characterized by NMR spectroscopy, ESI spectrometry, and single-crystal X-ray structural analysis. A detailed analysis of the side products revealed an unexpected carbon-carbon alkyne bond splitting promoted by the ruthenium(II) center, leading to the formation of a CO-RuII species, methyl-bipyridine, and a methyl-bipyridine-substituted ruthenium(II) complex accompanying the target product. The side products were characterized using complimentary methods including X-ray crystallography. A possible mechanism is suggested based on these side products and exemplary reaction studies. For the coordination reaction of alkyne-bipyridines with Ru(bpy)2Cl2 unexpected side reactions take place, forming a RuII-CO species and methyl-bipyridine. Here we give a detailed mechanism of the side reactions and an adequate workup procedure to obtain a pure alkyne-substituted ruthenium(II) polypyridine complex, which is the intended product.
