Six of the best: Benzene had been used by Faraday and Mitscherlich in their respective synthesis of hexachloro- and hexabromocyclohexane in the early 19th century. Also starting from benzene, η-1,2,3,4,5,6-hexafluorocyclohexane (benzene hexafluoride; see X-ray structure of a dimer) was now synthesized in five steps.
