摘要：

Reactions of R2SbH with BuLi at -70 degrees C in tetrahydrofuran (thf) lead to [R2SbLi(thf)(3)] [R = Ph (1) or R = Mes (2)]. The antimonides [tBu(2)SbK(pmdeta)] (3) (pmdeta = pentamethyl-diethylenetriamine), [Li(tmeda)(2)][tBu(4)Sb(3)]center dot benzene (4) (tmeda = tetramethylethylenediamine), and [tBu(4)Sb(3)Na(tmeda,thf] (5) result from the reduction of cyclo-(tBuSb)(4) by Li, Na, or K with pmdeta or tmeda in thf. The primary stibanes RSbH2 [R = Mes (6), 2-(Me2NCH2)C6H2 (7)] are synthesized by reactions of RSbCl2 with LiAlH4. PhSbH2 reacts with BuLi, and tmeda in toluene to give [Sb7Li3(tmeda)(3)]center dot toluene (8). [Sb7Na3(pmdeta)(3)]center dot toluene (9) is obtained from PhSbH2, Na in liqu. NH3, pmdeta and toluene. Crystal structures are reported for 1-5 and 9.
