Abstract

A series of 5-arylidene-2-thiobarbiturates was synthesized by Knoevenagel condensation from thiobarbituric acid under mild conditions; the use of water as a solvent allowed obtaining the target products in yields up to 78%. The addition reaction of dimethyl phosphite to 5-arylidene-2-thiobarbiturates was studied. The optimal conditions for this reaction were selected, and the high efficiency of cesium fluoride as catalyst was shown.

期刊介绍： Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
