Ef. Corsico et Ra. Rossi, Synthesis of mono-, di-, and tri-phenyl arenes by sequential photostimulated S(RN)1 and Pd(0)-catalyzed cross coupling reactions on aryl halides, SYNLETT, (2), 2000, pp. 230-232
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 m
echanism. These products reacted by a palladium-catalyzed cross coupling re
action with halobenzenes to give phenylated products also in very good yiel
ds. Similar yields can be obtained in one-pot reactions.
