Symmetrical, mononuclear bis(acetylido)ruthenium(II) complexes were prepared by the reaction of [ trans ‐RuMe 2 (dmpe) 2 ] [dmpe = 1,2‐bis(dimethylphosphanyl)ethane] with terminal alkynes. The complexes were characterised by multinuclear NMR spectroscopy and X‐ray crystallography. In some cases, the complexes catalyse the head‐to‐head dimerisation of terminal alkynes to yield organic butenynes. The regiochemistry of this dimerisation depends on the solvent used; methanol results in the isolation of ( Z )‐butenynes, whereas toluene gives predominantly ( E ) isomers.
