and practical method for the selective synthesis of diorganyl diselenides over diorganyl selenides are presented. Considering the discrepancies between reports on organoselenium compounds, we wanted to establish a tolerable synthetic method for diorganyl diselenides and investigate their characteristics. We optimized reaction conditions for sodium diselenide preparation using selenium, NH2NH2·H2O,
Bis(trimethylsilyl)selenide in the Selective Synthesis of β-Hydroxy, β-Mercapto, and β-Amino Diorganyl Diselenides and Selenides Through Ring Opening of Strained Heterocycles
dialkyl diselenides and selenides is described through reaction of bis(trimethylsilyl)selenide with epoxides, thiiranes, and aziridines catalyzed by tetrabutylammonium fluoride. Selective formation of a wide variety of β-hydroxy, β-mercapto, and β-amino diselenides and selenides is achieved by controlling the reaction conditions in the regioselective attack of the silylselenide onto the ring-strained
