    Description / Table of Contents: Spirobipyrans from o-Hydroxyarylvinylpyrylium SaltsStructurally defined o-hydroxyarylvinylpyrylium salts can be cyclized to spirobipyrans of type 1-5 and to the hitherto unknown 2,2′-spirobi[2H-naphtho[1,2-b]pyrans] (6). Asymmetric monosubstituted spirobipyrans of type 2, 3, and 5 show a correlation between thermochromism and position of the substituent (Table 1).
    Notes: Strukturspezifisch aufgebaute o-Hydroxyarylvinylpyryliumsalze werden zu Spirobipyranen der Typen 1-5 und zu den bisher unbekannten 2.2′-Spirobi[2H-naphtho[1.2-b]pyranen] (6) cyclisiert. Bei asymmetrisch aufgebauten, monosubstituierten Spirobipyranen der Typen 2, 3 und 5 wird ein Zusammenhang zwischen Thermochromie und Anordnung des Substituenten beobachtet (Tab. 1).
