Tröger base: Study of its complex with HgBr2 and its methiodide [D. Lenev, K. Lyssenko, R. Kostyanovsky] Reactions of the Tröger base (1) with HgBr2 and Mel proceed with the participation of only one N atom. According to the data of X-ray diffraction analysis, the complex [(±)-1]2·HgBr2 crystallizes in the achiral space groupP n . Unlike the complex [(+)-1]2·HgBr2, methiodide of (+)-1 in MeOH undergoes racemization at 20°C. The virtual spin-spin coupling constants4 J HH observed for the base (C 2 symmetry) are transformed into the "usual” constants in the case of the desymmetrized methiodide system.
