Two additional polyphenylated anthracenes, the 1, 8, 10-triphenyl derivative 5 and the 1, 8, 9, 10-tetraphenyl derivative 6, have been prepared by reaction of the diphenylquinone 2 with phenyllithium followed by reduction and dehydration. Mononitration of l&diphenylanthracene (la) yielded the 10-nitro derivative 13. Derivatives 12 of 1, 8- diphenylanthracene with a substJituent at C-9, a location allowing interaction of the ...
