20. Unfortunately, attempts to effect substitutive deamination of diamine 2 by treating it with tert-butylnitrite and copper-(II) bromide in acetonitrile (Doyle, M. P.; Siegfried, B.; Dellaria, J. F., Jr. J. Org. Chem. 1977, 42, 2426) gave a mixture that was contaminated with overbrominated compounds, in contrast to a reported result (Wu, F.-I.; Dodda, R.; Reddy, D. S.; Shu, C.-F. J. Mater. Chem. 2002, 12, 2983); the desired 2,2′-dibromo-9,9′-spirofluorene, however, could be isolated in low yield (<30%) upon recrystallization from toluene.

Chem. 2002, 67, 4924) to brominate at these positions regioselectively, but in our hands, this approach furnished complicated mixtures of brominated compounds from which 2,2′-dibromo-9,9′-spirobifluorene, which we intended to use as a precursor for the preparation of L, was isolated only in low yield after recrystallization several times from toluene.
