Abstract: Abstract Heterocyclic amines were diazotized and coupled with 8-anilinonaphthalene-1-sulfonic acid magnesium salt to synthesize some new heterocyclic monoazo dyes, showing ammonium-azonium tautomerism. The structures of the dyes were characterized by 1H‐NMR, MALDI, FTIR, and UV–Visible… read more here.

Abstract: Abstract Starting from the ethyl 1-aminothieno(furo)[2,3-b]pyridine-2-carboxylates 1 by alkaline hydrolysis the corresponding potassium salts of thieno(furo)[2,3-b]pyridines 2 were obtained. Ongoing to the relevant acids (by treatment with hydrochloric acid), we have observed that while thieno[2,3-b]pyridines… read more here.
