摘要：

A heterogeneous [Pd(NH3)(4)]-NaY catalyst was applied to the copper-free Sonogashira cross-coupling of aryl halides with terminal alkynes. This copper-free heterogeneous Pd-catalyst is efficient, stable and recyclable. Aryl iodides and activated aryl bromides were converted quantitatively using 1 mol% Pd-catalyst to the corresponding diaryl-substituted alkynes within 3 h. (C) 2003 Elsevier Ltd.
