摘要：

Three phosphine-funetionalised polymer resins were used as scavengers of palladium catalysts from Buchwald-Hartwig aryl amination reactions. The purity of the products was assessed, and residual palladium analysed by ICP-AES. Scavenging efficiencies of up to > 98.5% were demonstrated. (c) 2005 Elsevier Ltd. All rights reserved.
