palladium-catalyzed cross-coupling of 2-halotellurophene with several terminalalkynes to give the 2-alkynyl-tellurophene derivatives in excellent yields. The reaction proceeded cleanly under mild conditions and was performed with propargyl alcohols, propargyl amines, propiolate, as well as alkyl and aryl alkynes, in the presence of PdCl 2 (PPh3 ) 2 , Et 3 N, THF and Cul.
