Dedicated to Professor Herbert W. Roesky on the occasion of his 65th birthday

By attempting to generate a cationic, possibly solvated, vinylideneruthenium(ii) complex with a 14-electron configuration at the metal center, we recently found that the reaction of the starting material 1 with HBF 4 in dichloromethane/ diethyl ether leads to the formation of the ruthenium carbyne 3 instead of the anticipated ruthenium vinylidene 2 [Eq. ( 1)]. [1] Although compound 3 is a highly efficient catalyst
