palladium-catalyzed carbonylation of 2-haloselenophene and amines, under carbon monoxide atmosphere, giving a new route to prepare selenophene-2-carboxamides, selenophene-2,5-dicarboxamides and N,N′-bridged selenophene-2-carboxamides in good yields. The reaction proceeded cleanly under mild conditions, using a simple apparatus and procedure, and in the absence of high pressure of carbon monoxide. (© Wiley-VCH
