摘要

A Stille coupling reaction of organostannanes with organic halides has been developed in the presence of a catalytic amount of MCM-41-supported bidentate phosphine palladium (0) complex (0.5 mol%) in DMF/H2O (9: 1) under air atmosphere in high yields. This polymeric palladium catalyst exhibits higher activity than Pd (PPh3) 4 and can be reused at least 10 times without any decrease in activity.
