Beschreibungen/Notizen

• Tetraalkyldistibanes Sb2R4 (R = nPr, iBu) react with tBu3M (M = Al, Ga) at –30 °C with the formation of the Lewis acid–base adducts [tBu3M]2[Sb2R4] [M = Al, R = nPr (1), iBu (2); M = Ga, R = nPr (3), iPr 4)]. Compounds 1 and 2 are stable in solution whereas 3 undergoes a Sb–Sb bond‐breakage reaction with the subsequent formation of [tBu2GaSb(nPr)2]2 (5). The same trend was observed for the reaction of Sb2(iBu)4 with tBu3Ga, which yielded the heterocyclic stibanylgallane [tBu2GaSb(iBu)2]2 (6). In addition, the simple trialkylstibane adduct tBu3Al–Sb(iBu)3 (7) was obtained as a byproduct from the reaction of Sb2(iBu)4 with tBu3Al. Compounds 1–7 were characterized by multinuclear NMR (1H, 13C{1H}) and mass spectroscopy and elemental analysis. Compounds 1, 3, 5, and 7 were also investigated by single‐crystal X‐ray diffraction.
