A time-economical and robust synthesis of various selenofunctionalized heterocycles was accomplished via I2O5-mediated selenocyclizations of olefins with diselenides. Using this method, 116 selenomethyl-substituted heterocycles were

An intramolecular selenocyclizations of olefins mediated by a commercially available hypervalent iodine(III) reagent, PhIO, was developed. This method provided access to a wide range of selenenylated heterocycles under ambient conditions. The striking advantages of this protocol over all previous methods include mild reaction conditions, easy operation, good yields, high levels of functional group compatibility, large–scale application and suitability for the late-stage functionalization of complex molecules of biological importance.

Arylseleninic acids were used as an electrophilic selenium source in aromatic substitution reactions, using N,N-substituted anilines and indoles as nucleophiles at 70 °C for 6-15 h. A total of fourteen 4-selanylanilines and five 3-selanylindoles were selectively obtained in good to excellent yields. The starting benzeneseleninic acids are easily prepared from the respective diselenides, are bench stable and easy to handle, affording water as the only waste at the end of the reaction.
