Ean of dibenzene chromium

Bis(benzene)chromium is the organometallic compound with the formula Cr(η -C6H6)2. It is sometimes called dibenzenechromium. The compound played an important role in the development of sandwich compounds in organometallic chemistry and is the prototypical complex containing two arene … See more In the late 1910s, Franz Hein started the investigation of "triphenylchromium" by reacting chromium trichloride with a Grignard reagent, phenyl magnesium bromide. Such a reaction gave a mixture of phenyl chromium … See more The actual discovery of bis(benzene)chromium was largely contributed by Ernst Ottot Fischer and Walter Hafner in the 1950s. Ernst Otto Fischer postulated … See more The compound reacts with carboxylic acids to give chromium(II) carboxylates, such as chromium(II) acetate.
