✦ Synopsis

Abstract

Regioselective Suzuki cross‐coupling reactions of tetrabromoselenophene allow a convenient synthesis of aryl‐substituted selenophenes. High yields were obtained using a novel biaryl‐monophosphine ligand. The first tetra(1‐alkynyl)selenophene was prepared in one step by a Sonogashira reaction of tetrabromoselenophene.
