H. Schirmer et al., A SOLUBLE BENZODIFLUORANTHENE DERIVATIVE BY DEHYDRATION OF AN OXYGEN-BRIDGED PRECURSOR, Chemische Berichte, 126(11), 1993, pp. 2543-2546
Synthesis and characterization of the alkyl chain-substituted benzodif
luoranthene 6 are described. The final synthetic step involves an acid
-promoted dehydration whose conversion is determined to be quantitativ
e. The solubilities of compounds 4e, 5, and 6 are qualitatively correl
ated with structural features. The molecular structure of 6 in the cry
stal is elucidated by an X-ray structure analysis.
