文摘

E-Selective dimerization of phenylacetylene has been achieved. Tris(μ-hydroxo)diruthenium(II) acts as the catalyst. The C–H bond cleavage process is involved in this process. Kinetic study suggests this reaction to proceed at the dinuclear complex. This is the first kinetic study for alkyne dimerizations by a dinuclear complex.
