The coupling between aryl iodides and bromides with organostannanes (Stille reaction) has been investigated in the presence of a polymer supported palladium catalyst. The reaction could be performed in air without any activating ligand and with non-dried solvents. The catalyst, which acts by releasing controlled amounts of soluble active species, could be recycled several times in the coupling between Sn(CH3)(4) or "Bu3SnPh with iodoarenes or activated bromoarenes.

Abstract
The coupling between aryl iodides and bromides with organostannanes (Stille reaction) has been investigated in the presence of a polymer supported palladium catalyst. The reaction could be performed in air without any activating ligand and with non-dried solvents. The catalyst, which acts by releasing controlled amounts of soluble active species, could be recycled several times in the coupling between Sn(CH3)(4) or "Bu3SnPh with iodoarenes or activated bromoarenes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
