A Soluble Benzodifluoranthene Derivative by Dehydration of an Oxygen‐Bridged Precursor

Synthesis and characterization of the alkyl chain-substituted benzodifluoranthene 6 are described. The final synthetic step involves an acid-promoted dehydration whose conversion is determined to be quantitative. The solubilities of compounds 4e, 5, and 6 are qualitatively correlated with structural features. The molecular structure of 6 in the crystal is elucidated by an X-ray structure analysis.
