ChemInform Abstract: Selective Base-Promoted Synthesis of Substituted Selenophenes by Carbocyclization of (Z)-Benzylselenoenynes

Hydroselenation of diaryldiynes (II) with dibenzyl diselenides (I) affords benzylselenoenynes (III) which smoothly undergo cyclization in the presence of the strong base tBuOK to give 3‐benzyl‐2,5‐diaryls selenophenes (IV).
