Abstract:
: A series of novel 2-S-, 4-, 5-substituted and bicyclic 6-methylpyrimidine-4-ol derivatives including pyrazole, 1,2,4-triazole and pyridazine moieties in the molecule were synthesized by accessible and efficient methods. Thiopyrazolyl derivatives were obtained from 2-mercapto-6-methylpyrimidin-4-ol. 4-Triazolyl and 4-aminotriazolylpyrimidines were synthesized from the quaternary ammonium salt of pyrimidine and 4-chloro-substituted 2-thiomethyl-6-methylpyrimidine, respectively.

Abstract:
The selective and sensitive hyphenated technique for Pd(II) fluorescence and spectrophotometric determination was proposed. The procedure was based on preliminary solid-phase extraction of [PdCl4]2− onto silica modified with quaternary ammonium salts, with the subsequent elution from the surface by 2,6-diamino-1- N-methylpyrimidine solution and measurement of the fluorescence intensity. The luminescence enhancement effect of 2,6-diamino-1- N-methylpyrimidine in the presence of Pd(II) due to the complex formation was applied to the development of sorption-spectroscopic techniques for detecting
