The complex [Ru(η 5 ‐C 7 H 11 ) 2 H]BF 4 (C 7 H 11 = 2,4‐dimethylpenta‐2,4‐dienyl) is highly reactive towards two‐ and six‐electron ligands. e.g. giving with CO complex [RuCO(η 4 ‐C 7 H 12 )(η 5 ‐C 7 H 11 )]BF 4 . The 2,4‐dimethylpenta‐1,3‐diene ligand (C 7 H 12 ) of the latter complex is readily displaced giving, e.g. with excess cyclohexa‐1,3‐diene (C 6 H 8 ) complex [RuCO(η 4 ‐C 6 H 8 )(η 5 ‐C 7 H 11 )]BF 4 . These reactions provide a convenient entry into monopentadienylruthenium chemistry.
