Abstract

The reactions of the ruthenium hydride complexes [(Ru(COD)(H)(NH₂NMe₂)₃)(BAr^F)] (BAr^F═[B(C₆H₃(CF₃)₂)₄), [(Cp*Ru)₂(μ-H)₄] and [(Cp*Ru)₃(μ-H)₃(μ³-H)₂] with GaCp* and AlCp* are investigated. The reaction of [(Ru(COD)(H)(NH₂NMe₂)₃)(BAr^F)] with GaCp* leads to substitution of the hydrazine ligands by GaCp* and the formation of [(Ru(COD)(H)(GaCp*)₃)(BAr^F)] (1), while the reactions of [(Cp*Ru)₂(μ-H)₄] and [(Cp*Ru)₃(μ-H)₃(μ³-H)₂] with ECp* (E = Al, Ga) results in the formation of the polyhydride clusters [(Cp*Ru(μ-H)(H)(μ-ECp*))₂] (2, E = Ga; 3, E = Al) and [(Cp*Ru)₃(μ-H)₅(μ³-ECp*)] (4, E = Al; 5, E = Ga). All Ru complexes react upon coordination of the group 13 ligand without loss of H₂ or reductive elimination of Cp*H and without insertion into the Ru–H bonds; some of the products, however, showing Ru–H–E bridging motifs. All compounds were characterized by NMR spectroscopy, elemental analysis and single crystal X-ray diffraction studies.
