operationally simple homocoupling reaction that targets the convenient synthesis of organic-electronically important building blocks. A variety of synthetically useful bithiophene derivatives and functionalized biphenyls are efficiently prepared by an on-water and under-air protocol using Pd/C as catalyst. We find that Pd/C gives generally higher and cleaner homocoupling conversions than using Pd(OAc)2 in the

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
