Synthesis of mono-, di-, and tri-phenyl arenes by sequential photostimulated S(RN)1 and Pd(0)-catalyzed cross coupling reactions on aryl halides

摘要

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