Abstract:

The Friedlander quinoline synthesis was applied to 4,6-diaminoisophthaldehyde. This compound was condensed with acetophenone, 2-acetylpyridine, 4-acetyldiphenylether and phenylacetaldehyde yielding the corresponding anthrazolines Pyrido2,3-gquinolines. These model reactions were then applied to the polycondensation of 4,6-diaminoisophthaldehyde with p-diacetylbenzene, 2,6-diacetylpyridine and bisp-acetylphenylether. The resulting polymers have a high thermal stability as revealed by thermogravimetric analysis 620C break under nitrogen. The extension of the Friedlander quinoline synthesis in the pyridine series was investigated, resulting in new syntheses for 2-amino-3-formylpyridine and 2,6-diamino-3,5-diformylpyridine. Author
