摘要：

A very convenient general method was developed for making tunable polypropylene-supported Pd complexes of electron-rich and bulky monodentate ligands such as Q-Phos, t-Bu3P, (Me2NC6H4)P(t-Bu)(2) (A(ta)-Phos), and IPr-carbene as well as bidentate ligands such as BINAP, dppf, and dippf in 4-8% Pd loading. These catalysts have been utilized for Suzuki coupling of aryl chlorides and bromides with product conversions up to 100%. Minimal metal leaching has been observed in many cases. Many of these catalysts were recycled a few times in model systems with an undetected amount of Pd leaching.
