An efficient heterogeneous copper-free Sonogashira-Hagihara coupling reaction was performed in the presence of 2-aminophenyl diphenylphosphinite (L) as a ligand, Pd(OAc) 2 and a base in neat water at 25-95 • C. By this protocol, different aryl halides (Cl, Br, I) were reacted with phenylacetylene in
