Solid-phase Suzuki cross-coupling reactions using a phosphine ligand based on a phospha-adamantane framework
摘要:
The use of a catalyst system based on Pd(2)dba(3.)CHCl(3) and 1,3,5,7-tetramethyl-2,4,8-trioxa-6-phenyl-6-phosphaadamantane allows for Suzuki coupling aryl halides with an array of boronic acids on a solid-phase platform. The reactions can be carried out at room temperature with low palladium loadings in high yields. (C) 2004 Elsevier Ltd. All rights reserved.
