Telluropyrylium salts

Doddi, G., Ercolani, G., Thiopyrylium, Selenopyrylium, and Telluropyrylium Salts, 60, 65. [Pg.289]

Sterically hindered seleno- and telluropyrylium salts 40 react with squaric acid 41 <1993H(35)1149> and also with 4,5-dihydroxy-4-cyclopentene-l,2,3-trione (croconic acid) 42 <2000JOC2236> in the presence of base to afford squarylium and croconate dyes 43 and 44, respectively (Equations 11 and 12). Dyes of this type have important industrial applications (Section 7.11.8.2). [Pg.964]
