Unexpected Ligand Displacement of Ru(cod)(cot) with Trimethylphosphine to Give fac-Ru(6-η1:1-3-η3-C8H10)(PMe3)3

Selective ligand displacement of the cod ligand in Ru(cod)(cot) (1) [cod: 1,5-cyclooctadiene, cot: 1,3,5-cyclooctatriene] with trimethylphosphine gives fac-Ru(6-η1:1-3-η3-C8H10)(PMe3)3 (3) in benzene at 50 °C.
