Abstract
The Suzuki–Miyaura reaction has been performed using a phosphine-free perfluoro-tagged palladium catalyst that is readily immobilized on fluorous silica gel through fluorous–fluorous interactions (Pd-1/FSG). The reactions are carried out under aerobic and phosphine-free conditions with excellent to quantitative product yields, and very low palladium content (< 0.8 ppm) in the products was detected by ICP-AES. The catalyst can be recovered by simple filtration and reused several times without significant loss of activity.
