  • Note di contenuto: RuHCl(PPh 3) 3 reacts quantitatively with cycloheptatriene in CH 2Cl 2 at 35°C in 15 min to give Ru(η 5-C 7H 9)Cl(PPh 3) 2 and PPh 3. The major isomer adopts a conformation with inequivalent phosphorus ligands and no plane of symmetry through the C 7H 9 ligand, but rapid intramolecular scrambling with δ G ‡ = 10.6 kcal mol −1 results in an averaged 1H, 13C, and 31P NMR spectrum at room temperature. RuHCl(PPh 3) 3 reacts with cyclohepta-1,3-diene to give initially Ru(η 3-C 7H 11)Cl(PPh 3) 2, but in a subsequent reaction this is dehydrogenated to give Ru(η 5-C 7H 9)Cl(PPh 3) 2.
