Abstract

Symmetrical tetra-tert-butyl-substituted pyrylo-2- and thiopyrylo-2-monomethinecyanines were synthesized by the condensation of 2-methyl-4,6-di-tert-butylpyrylium and -thiopyrylium salts, respectively, with 2-(alkylthio)-4,6-di-tert-butylpyrylium and -thiopyrylium salts. The pyrylo-2-cyanine obtained was converted to a tetra-tert-butyl-substituted pyrido-2-monomethinecyanine by treatment with methylamine. It was shown by PMR spectroscopy that, in contrast to pyrido-2-monomethinecyanine, which exists in the E,E form, its oxygen-containing analog exists in the E,Z form, and its sulfur-containing analog exists in the Z, Z configuration.
