Pyrylocyanines. Part 35. Squarylium Dyes Derived from tert-Butyl Substituted Pyrylium and Thiopyrylium Salts. -The synthesis of squarylium dyes (cf. (III), 9 examples) by condensation of pyrylium or thiopyrylium salts with squaric acid and their characterization by IR and NMR spectroscopy is presented. -(KURDYUKOV, V. V.; KUDINOVA, M. A.;
