Spectrophotometric Determination of Cu2+ and Monitoring of Hg2+ and Ni2+ in some Iranian Vegetables Using 6-(2-Naphthyl)-2, 3-Dihydro-as-triazine-3-thione
Recently, 6-(2-naphthyl)-2, 3-dihydro-as-triazine-3-thione (NDTT) was synthesized in laboratory and used successfully for the spectrophotometric determination of nanogram levels of Cu2+ in aqueous solution. This reagent forms a specific red complex with Cu2+ ions after the extraction by chloroform at alkaline pH. The absorption of the complex in the UV region (313 nm) is about 8 times as strong...

15 صفحه اولAn Expeditious Synthesis of New 5-acetyl-4-(4’-alkyloxyphenyl)- 3-cyano-6-methylpyridine-2(1H)-thiones and Derivatives
A convergent synthesis of 5-acetyl-4-(4'-alkyloxyphenyl)-3-cyano-6-methylpyridine-2(1H)-thiones and their derivatives S-alkylthiopyridines was described. The main steps towards the formation of the title compounds involve the reactions of 4-alkyloxybenzaldehydes with 2-cyanothioacetamide to afford 2-cyano-3(4'-alkyloxyphenyl)prop-2-enethioamides which then reacted with acetylacetone prior to th...
متن کاملcatena-Poly[sodium [[tris(3-methylpyridine-2-carboxylato)europate(III)]-μ-3-methylpyridine-2-carboxylato] trihydrate]
In the title structure, {Na[Eu(C(7)H(6)NO(2))(4)]·3H(2)O}(n), the Eu(III) atom is nine-coordin-ated within a slightly distorted tricapped trigonal-prismatic coordination geometry defined by five carboxyl-ate-O atoms and four pyridine-N atoms. One of the carboxyl-ate ligands bridges the Eu cations, forming a one-dimensional coordination polymer along the b axis. The Eu-O bond distances lie withi...
