| Abstract: | The direct interaction of 2,6-diphenylpyrylium perchlorate with pyrazoles and pyrazolones led to the synthesis of 4-azolylpyrylium salts, which readily cleave a molecule of perchloric acid in the case of the N-unsubstituted pyrazolones, being converted to pyranylidene derivatives.For Communication 15, see 1].Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 2, pp. 182–187, February, 1987. |
