Syntheses and crystal structures of two bulky aminohalostannanes, [(Me3Si)2CH]2Sn(Cl)N(H)(C6H2-2,4,6-tert-Bu3) and [(Me3Si)2CH]2Sn(F)N(H)(C6H2-2,4,6-tert-Bu3).
The sterically hindered aminohalostannanes (Bis)2Sn(X)N(H)Ar [X = Cl, F; Bis = (Me3Si)2CH; Ar = 2,4,6-(Me3C)3C6H2] were prepd. in good yield by the reactions of the lithium salt of the amine ArNH2 with the (Bis)2SnX2. Their NMR spectra (1H, 19F, 119Sn) are described. The structures of these new compds. have been detd. by x-ray crystallog.
