Abstract
An experimentally straightforward procedure for the synthesis of structurally elaborate cyclohexadienyl ruthenium(II) complexes has been developed along the lines of the Morita - Baylis - Hillman reaction. Coordination of (cyclopentadienyl)Ru(II) fragments to N-benzyl and N-phenethyl acrylamides was found to facilitate conversion to stable cyclohexadienyl complexes via Bu 3P-mediated intramolecular cyclization. An ipso cyclization was observed in all but one case, resulting in formation of five- or six-membered spirolactams at C6 positions of cyclohexadienyl ligands. Acrylamides prepared from dihydroindene and tetrahydronaphthalene precursors were suitable substrates for this transformation, affording access to novel tricyclic cyclohexadienyl complexes. One such complex was characterized by X-ray crystallography. © 2009 American Chemical Society.
