摘要: Abstract Infrared studies at a CO pressure of 120 bar show (η 5 -C H ) 2 W(CO) to be completely resistant an excess in the absence oxidants, but cyclovoltammetric measurements with this complex and 3 )(η )W(CO) THF solution 0°C indicate that ring-slipped dicarbonyl is catalytically generated by one-electron oxidation tungstenocene monocarbonyl under ambient pressure. Similar results are found for reaction Mo(CO) CO.
