 note = {The preparations, reactions and functionalities of two types of the pyrylium salts (1- and 2-seleno- or telluro-pyrylium salts) are described. The 1-benzoselenopyrylium and 1-benzotelluropyrylium salts were prepared from the corresponding chromen-4-ones by the reduction and treatment with triphenylcarbenium tetrafluoroborate in two steps. The 2-benzoselenopyrylium and 1-benzotelluropyrylium salts were obtained from the isochromenes. The sensitive stability to the nature of the substituents at the C-2 or C-3 positions on the pyrylium salts and the reactions with several nucleophiles including alkoxides, amines, cyanide ion, an active methyl compound (acetone) and Grignard reagents, and also hydrogenation and hydrolysis are described. The precursors, benzochromones and isochromenes have been obtained by the intramolecular cyclization of tellurols, selenols and related compounds to a triple bond as the synthetic strategy in the previous review.},
