The reaction of nona-2,7-diyne, deca-2,8-diyne and hex-1-yne with [RuCp(PR3)(MeCN)2]PF6 (R = Cy, Ph, Me) affords, depending on the structure of the alkyne and the substituent of the phosphine ligand, ruthenium metallacyclopentatriene, allyl carbene and/or butadienyl carbene complexes involving either metal-to-ligand-to-metal migration of the phosphine ligand with concomitant C-H activation or a facile 1,2 hydrogen shift.
