(E,E)‐1,6,11‐Tris(arenesulfonyl)‐3,4‐benzo‐1,6,11‐triazacyclopentadeca‐8,13‐dienes (2) and 1,6,11‐tris(arenesulfonyl)‐3,4; 8,9;13,14‐tribenzo‐1,6,11‐triazacyclopentadecanes (3) were prepared from arenesulfonamides, trans‐1,4‐dibromobutene, and 1,2‐bis(bromomethyl)benzene. They form unstable complexes with silver tetrafluoroborate. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
