Synthesis, structure and some reactions of (C5Me4hex)2Ru2(CO)4

The synthesis of the new cyclopentadiene, C5Me4(hex)H is described and its reaction with Ru3(CO)12 to yield (C5Me4hex)2Ru2(CO)4 (hex = n-hexyl) is reported. The X-ray crystal structure of the dimer confirms the structure with bridging and terminal CO groups. Reactions of the dimer to yield (C5Me4hex)Ru(CO)2X (X = Cl, Br, I) are reported. IR, NMR and mass spectra are reported for all new compounds. The solubility of the dimer is found to be 10 times greater than that for (C5Me5)2Ru2(CO)4.

Tetramethylhexylcyclopentadienyl ruthenium dicarbonyl dimer has been prepared and characterized. Halide derivatives of this complex have been prepared. It is found that complexes with this cyclopentadienyl ligand are much soluble than pentamethylcyclopentadienyl anologs.Figure optionsDownload as PowerPoint slide
