Rhodocene
Rhodocene, formally known as bisrhodium, is a chemical compound with the formula 2. Each molecule contains an atom of rhodium bound between two planar aromatic systems of five carbon atoms known as cyclopentadienyl rings. Rhodocene derivatives are used to synthesise linked metallocenes. Potential applications of these derivatives include molecular electronics and research into the mechanisms of catalysis.
About Rhodocene in brief
Rhodocene, formally known as bisrhodium, is a chemical compound with the formula 2. Each molecule contains an atom of rhodium bound between two planar aromatic systems of five carbon atoms known as cyclopentadienyl rings. The 2 radical is found above 150 °C or when trapped by cooling to liquid nitrogen temperatures. Discoveries in organometallic chemistry have led to important insights into chemical bonding. One potential application for a rhodocene derivative as a radiopharmaceutical to treat small cancers. Rhodocene derivatives are used to synthesise linked metallocenes so that metal–metal interactions can be studied. Potential applications of these derivatives include molecular electronics and research into the mechanisms of catalysis. The discovery of ferrocene, 2, was first synthesised in 1951 during an attempt to prepare the fulvalene by oxidative dimerization ofcyclopentadiene; the resultant product was found to have molecular formula 10H10H10. It sparked substantial interest in the field of organometallic chemistry in part because the structure proposed by Pon and Kealy was inconsistent with existing bonding models and did not explain its stability. Consequently, the initial challenge was to determine the structure and properties of Ferrocene in the hope that its bonding and properties would then be understood. The sandwich structure was deduced and independently investigated by three groups in 1952: Robert Burns Woodward, Geoffrey Wilkinson and Ernst Otto Fischer: Eiland, Pepinsky and Wilkinson.
They demonstrated that ferrocenes undergo similar reactions to a typical aromatic molecule and demonstrated the reactivity of cobaltocene in order to determine its structure and reactivity. The work on sandwich compounds, including the rhodocenium-rhodocene system, earned Geoffrey Wilkinson the 1973 Nobel Prize for Chemistry. The value of rhodocenes tends to be in the insights they provide into the bonding and dynamics of novel chemical systems, rather than their applications. The study of organomet metallic species including these ultimately led to the development of new bonding models that explained their formation and stability. It is hoped that this article will help scientists to better understand the chemistry of the metallocene class of compounds, such as CFe and CFeFe, and to find out how they interact with each other and with other metals and other compounds in a variety of ways.
