摘要
Sulfonato-Cu(salen) complex immobilized onto a Merrifield's resin was found to be an efficient catalyst for the N-arylation of heterocycles with electron-withdrawing hloro- and fluoroarenes. The reactions were carried out in the presence of an inexpensive mild base, K2CO3, and N-arylated compounds were obtained in good to excellent yields. The catalyst was recovered by simple filtration and reused for three cycles with almost consistent activity.
