The photostimulated reaction of Me3Sn- ion with mono, di and trichloro aren
es in liquid ammonia gave very good yields of stannanes by the S(RN)1 mecha
nism. These products reacted by a palladium-catalized cross coupling reacti
on with halobenzenes to give phenylated products also in very goods yields.
Similar yields can be obtained in one-pot reactions.
