| Abstract: | The acid–base chemistry of some ruthenium ethyne-1,2-diyl complexes, {Ru(CO)2(η-C5H4R)}2(μ2-C C)] (R=H, Me) has been investigated. Initial protonation of {Ru(CO)2{η-C5H4R}}2(μ2-CC)] gave the unexpected complex cation, crystallised as the BF4 salt, {Ru(CO)2(η-C5H4R}}3(μ3-CC)]BF4] (R=Me structurally characterised). This synthesis proved to be unreliable but subsequent, careful protonation experiments gave excellent yields of the protonated ethyne-1,2-diyl complexes, {Ru(CO)2{η-C5H4R)}2(μ2-η1:η2-CCH)](BF4) (R=Me structurally characterised) which could be deprotonated in high yield to return the starting ethyne-1,2-diyl complexes. |
