IR spectral data reveal that the 18-electron species (C 5 H 5 ) 2 Cr(CO) is reversibly transformed, at elevated CO pressures into a dicarbonyl complex, (C 5 H 5 ) 2 Cr(CO) 2 . Close coincidence of the v (CO) absorption bands of this dicarbonyl with t

Equilibria and kinetics in the CO-induced, reversible disproportionation of ((C5H5)2TiCl)2 to (C5H5)2TiCl2 and (C5H52Ti(CO)2. An IR study at elevated CO gas pressures

IR studies of toluene solutions of ((C 5 H 5 ) 2 TiCl) 2 under elevated CO pressures indicate the formation of a carbonyl complex, probably (C 5 H 5 ) 2 Ti(CO)Cl, with ν(CO) 2068 cm − . This species predominates at CO pressures above 100 bar, and

(C5H5)2Cr(CO), formed from chromocene and CO gas in THF solution at 0°C, loses its CO ligand upon one-electron oxidation. No CO loss is observed, on the other hand, when the ansa-chromocene carbonyl complex (CH3)4C2(C5H4)2Cr(CO) is oxidised to its m

CO-induced ring-slippage reactions of molybdenocene and tungstenocene carbonyl complexes : Electrochemical and elevated-pressure infrared evidence for an electron-transfer catalysis

Autor: Sigrid Mönkeberg, Edith U. van Raaij, Hans-Herbert Brintzinger, Herbert Kiesele

Infrared studies at a CO pressure of 120 bar show (η5-C5H5)2W(CO) to be completely resistant to an excess of CO in the absence of oxidants, but cyclovoltammetric measurements with this complex and with (η3-C5H5)(η5-C5H5)W(CO)2 in THF solution at 0
