Article abstract of DOI:10.1246/cl.1991.2051

From measurements of fluorescence and triplet-triplet absorption spectra of bromoanthracenes in acetonitrile-amines, it is concluded that bromoanthracene radical anions produced by a reaction of the lowest singlet states of bromoanthracenes with amines are the intermediates for the debrominations.
