The synthesis of novel organoselenium heterocyclic compounds is of great theoretical and practical interest because of high biological activity. The known methods of synthesis of hexatomic selenium containing heterocyclic compounds allow us to obtain only monoaryl-substituted tetrahydroselenochromilium salts. In this study, the reactions of 2-(3-oxo-1-aryl-3-phenylpropyl) cyclohexanones were carried out with hydrogen selenide in situ under conditions of acid catalysis in diethyl ether.
