Resumen:
The reaction of different ArCl with the Me2Sn2- dianion in liquid ammonia under irradiation afforded Ar2SnMe2 in good yields (68-85%). The results obtained clearly indicate that the reaction proceeded through an SRN1 reaction. As a synthetic application of these Ar2SnMe2, the homocouplingis described in the presence of Cu(NO3)2.2.5H2O to afford the biaryls. These reactions proceeded almost quantitatively.
