Polarographic study of 4-hydroxycoumarins with nitrogen-linked substituents in 3-position, and of 3-nitro-4-aminocoumarin

Autor: Z. Stunić, M. Trkovnik, M. Laćan

Publikováno v: Electrochimica Acta. 24:851-858

The polarographic behavior of 3-nitro-(I), 3-nitroso-(II),3-phenylazo-4-hyroxycoumarin (III) and 3-nitro-4-aminocoumarin (IV) has been investigated in aqueous-ethanolic media. The reduction mechanism of I, II, III and IV was proposed according to the

Reaction of 4-chloro-3-nitrocoumarin with glycine and alanine, and the synthesis of 1-benzopyrano[3,2-c]pyrimidine-3,5-dione

Autor: R. Janković, M. Trkovnik, Z. Stunić, M. Laćan

Publikováno v: Journal of Heterocyclic Chemistry. 18:511-513

A considerable improvement of the yields obtained in substitution of halogens in 4-chloro-3-nitrocoumarin by amino acid or amino acid ester residues was achieved over literature claims. Electrochemical reduction of the nitro group in these products b

Publikováno v: Croatica Chemica Acta
Volume 47
Issue 4

The electrochemical reduction of acetonylacetone on a mercury cathode in aqueous hydrochloric acid medium has been studied. It has been shown that the electroactive species is the protonated form of acetonylacetone. The experimental results indicate
