The reaction of the allyl-substituted system 5a with the reagent [Ru(PPh3)3Cl2] gave the [(κ3N,N′,N′′-chelate ligand)(PPh3)RuCl2] complex 6a, featuring a pair of cis chloride ligands. In contrast, the reactions of 5bd with [RuCl2(p-cymene)]2 yielded the complexes 7bd. They each feature a pair of trans chloride ligands and an internally coordinated η2-CHCH2 group at the octahedrally coordinated ruthenium center. Treatment of 7c,d with PMe3 resulted in a replacement of the internally coordinated π-olefin from ruthenium by the phosphine to yield the complexes 8c,d. The compounds 6a, 7bd, and 8c,d were characterized by X-ray diffraction. %I ACS Publications
