The internally cyclometalated complex (MeSi-(CH2PMe2)2CHPMe2(PMe3 )RuH has been prepared by the treatment of MeSi(CH2PMe2)3PMe3Ru(H)(Cl) with base, and an analogue has been structurally characterized by X-ray diffraction. The externally cyclometalated isomer MeSi(CH2PMe2)3PMe2CH2RuH has been cleanly generated by the thermolysis of MeSi(CH2PMe2)3PMe3Ru(H)(Me), and the two isomers have been contrasted in terms of their spectroscopic features, calculated energies, and relative reactivities toward cresol and H2. The two isomers are surprisingly resistant to interconversion. A chloride derivative, (MeSi(CH2PMe2)2CHPMe2)(PMe3 )RuCl, has also been prepared, and its reactivity has shown the internally cyclometalated framework to be surprisingly stable.
