摘要：

Polymer-supported palladium catalysts were prepared from three commercially available phosphine-functionalised polymers (PS-PR2), Pd-2(dba)(3) and P(t-Bu)(3). Catalyst stability was investigated using VT P-31 NMR spectroscopy. One of the catalysts can be reused in the amination of bromobenzene and chlorotoluene, up to three times, without loss in yield. Recyclability of the catalysts is dependent on the method of preparation and the nature of the polymer-bound phosphine. (c) 2005 Elsevier Ltd. All rights reserved.
