Résumé     
The synthesis of two new vinyltin reagents grafted on an insoluble macroporous polymer is reported. These reagents were used in the palladium-catalyzed Stille cross-coupling reaction with aryl halides. In all reactions, the conversion of the starting aryl halide is high and the amount of organotin by-product is particularly low (at the end of the catalytic run, the amount of Sri is up to 16 ppm in the crude reaction mixture removed of the insoluble polymer, and it is less than I ppm in the product purified by chromatography on silica gel).
