The reaction of iodoamide 1a or iodocarbamates 1b,c with electrophilic olefins 2a-e and in situ generated tributyltin hydride (from tributyltin chloride in a substoichiometric amout and an excess of sodium borohydride) in the presence of a catalytic amount of AIBN in dry ethanol at 0 to 20 deg C yields, after treatment with aqueous sodium fluoride, the expected coupling products 3aa-ce in moderate yields.Compounds 4a-c resulting from an iodine/hydrogen exchange in the starting materials 1a-c are also obtained as by-products in variable amounts.Parablas Clave: radicales β-funcionalizados, yodoamidas, formacion de enlaces C-C
