2-haloselenophenes with terminalalkynes catalyzed by PdCl2(PPh3)2, under co-catalyst free conditions and establish a new procedure to prepare (2-alkynyl)-selenophenes in good yields. The reaction proceeded cleanly under mild reaction conditions and was performed with propargylic alcohols, protected propargylic alcohols, propargylic amines, as well as alkyl, and aryl alkynes, in the presence of PdCl2(PPh3)2
