Through a combination of salt-elimination and oxidative-addition processes, three new Sn(IV) compounds have been prepared. The derivatives Sn(X)(NRAr)(3) (X = CH3, I; R = C(CD3)(2)CH3 Ar = 3,5-C(6)H(3)Me(2)) were prepared via an ''ate'' complex formulated as LiSn(NRAr)(3), whereas Sn(I)(CH3)(NRAr)(2) was obtained by addition of methyl iodide to Sn(NRAr)(2).
