Treatment of (p-cymene)Ru2(μ-Se2)(S2C2B10H10)2 (1) with (cyclo-C6H10)(OH)C≡CH in dichloromethane led to addition complexes, (p-cymene)Ru2(μ-Se2)(S2C2B10H10)2(R1C=CR2) [R1=H, R2=(cyclo-C6H10)(OH) (2); R1=(cyclo-C6H10)(OH), R2=H (3)]. In boiling chloroform both 2 and 3 spontaneously lose water to generate two geometrical isomers (p-cymene)Ru2(μ-Se2)(S2C2B10H10)2 (R1C=CR2) [R1=H, R2=cyclo-C6H9 (4); R1=cyclo-C6H9, R2=H (5)], respectively. Complexes 4 and 5 could be interconverted in refluxing toluene. In all products alkyne addition occurs at the sulfur atoms of the two individual chelating 1,2-dicarba-closo-dodecaborane-1,2-dithiolate ligands that leads to a change of the 16e Ru(IV) center in 1 to the 18e Ru(II) center in 25. The molecular structure of complex 2 has been determined by X-ray crystallography. All these complexes were characterized by elemental analysis, mass and NMR spectroscopy.

Key words: ortho-carborane, (cyclo-C6H10)(OH)C≡CH, chalcogenide element, ruthenium complexes, synthesis
