( 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)
