Use of silver oxide in the synthesis of areneruthenium metallacyclic complexes

Abstract

Silver oxide has been used as a base and halide abstracting agent in the synthesis of areneruthenium metallacyclic complexes of dianionic chelating ligands. The structures of [Ru{N(COMe)C(CHR)C(O)O}(PPh₃)(arene)] (R = Ph, arene = p-cymene; R = H, arene = C₆H₃Me₃-1,3,5) have been determined by X-ray diffraction. The scope of this methodology has been investigated and is not as great as for related platinum complexes.
