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 Sn is up to 16 ppm in the
