Synthesis of functionalized diaryldimethylstannanes from the Me2Sn2- dianion by SRN1 reactions.
[reaction: see text] The reaction of different ArCl with the Me(2)Sn(2)(-) dianion in liquid ammonia under irradiation afforded Ar(2)SnMe(2) in good yields (68-85%). The results obtained clearly indicate that the reaction proceeded through an S(RN)1 reaction. As a synthetic application of these Ar(2)SnMe(2), the homocoupling is described in the presence of Cu(NO(3))(2).2.5H(2)O to afford the biaryls. These reactions proceeded almost quantitatively.
