Synthesis of arylseleno-1,2,3-triazoles via copper-catalyzed 1,3-dipolar cycloaddition of azido arylselenides with alkynes
The use of organoselenium compounds in the copper-catalyzed Huisgen 1,3-dipolar cycloaddition of azido arylselenides with various alkynes is described. Arylseleno-1,2,3-triazoles are prepared in excellent yields via reaction of amino arylselenides with is

Synthesis of azido arylselenides and azido aryldiselenides: a new class of selenium-nitrogen compounds
We present here our results of the efficient synthesis of azido arylselenides and azido aryldiselenides under mild conditions. Starting from nitrogen-substituted benzenes, we incorporated selenium atom at aromatic ring and obtained amino arylselenides and diselenides in satisfactory yields. Treatment of these compounds with iso-pentyl nitrite (i-C5H11ONO) and azido trimethylsilane (Me3SiN3) in THF affords a variety of azido arylselenides and diselenides in good to excellent yields.
