Reactions of Ru(η4-1,5-COD)(η6-1,3,5-COT) (1) (COD = cyclooctadiene, C8H12; COT = cyclooctatriene, C8H10) with a series of Lewis bases are studied. Treatments of 1 with P(OMe)3, P(OEt)3, P(OMe)2Ph, P(OEt)2Ph, P(OiPr)3, P(OMe)Ph2, or P(OEt)Ph2 lead to the formation of Ru(η4-1,5-COD)(η4-1,3,5-COT)L (2) followed by preferential liberation of the 1,5-COD ligand to give COT complexes formulated as Ru(6-η1:1−3-η3-COT)L3
