Summary on Grant Application Form
Benzene (C6H6) is one of chemistry's most important molecules. It is a key industrial solvent and precursor in the production of drugs, plastics, gasoline, synthetic rubber, and dyes. The sweet-smelling aromatic compound was discovered in 1825 by Michael Faraday and its delocalised cyclic 'aromatic' structure was first proposed 40 years later by Friedrich August Kekule von Stradonitz. Here we are attempting to isolate the first new aromatic form of benzene since that time. Rather than having the 'normal' six-pi electron configuration, the new form will have ten pi electrons and therefore be tetra-anionic. Such a configuration was recently predicted by theoretical chemists to be stable when coordinated to two barium ions in a so-called inverted sandwich configuration. If we can translate this from a computer prediction to an isolable molecule it will be the first new form of aromatic benzene to be found in 140 years!
