摘要：

The Suzuki cross-coupling reaction of a boronic acid and a bromoaromatic compound requires palladium catalysis. Almost identical yields were obtained in the usual conditions, with 30 mequiv. of Pd(PPh3)(4), and with 2 mequiv of a polymer-supported catalyst, which was easily prepared in two steps from Merrifield polymer. Recovery and reuse of the catalyst is easy, and only 0,60% of the initial amount of palladium is lost during a reaction. (C) 1998 Elsevier Science Ltd. All rights reserved.
