Abstract

The preparation of selenophenes is here reviewed. Although it does not include the synthesis of fused rings systems with selenophenes, the entire range of reactions is covered: from acetylenes, olefins, β- diketo compounds, furan, imine, amide, cycle contraction using sodium selenide, cycloaddition, radical cyclisation and much more.

Keywords: selenophenes, heterocycles, selenium, ring closure, selenide, cyclisation
