摘要：

Palladium(0)-catalyzed cross-coupling reactions of electron deficient aryl- and heteroaryl bromides with aza-crown ethers of various ring sizes are described. The catalyst system Pd(OAc)(2)/PPh3 gave best results for cross coupling reactions of macrocyclic aza-crown ethers with electron poor aryl bromides.
