摘要

Unsymmetrically substituted 1, 8-diarylanthraceries where the aryl rings are m-tolyl (5), o- tolyl (6), and 2, 3-dimethylphenyl (7) have been synthesized; the barriers to aryl ring rotation in these hydrocarbons were found to be 5.3, 10.4, and 16.3 kcal/mol, respectively. Addition of either an acetoxyl (14) or a methyl (15) substituent at C-9 of the dixylylanthracene gave mixtures of cis and trans isomers that also exhibited rotation of an aryl ring within the ...
