A new highly reactive heptacarbon chain carboxonium salt 1 was synthesized. It leads, by action of various amines and hydrazone, to a new class of symmetrical heptacarbon chain streptocyanine dyes 2 − 6 . A hemicarboxonium salt 7 , which leads to a dissymmetrical streptocyanine, was also obtained. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
