, p. 9625 - 9627 (2008/10/09)
The bis(stibido) complex CpCp*Hf(SbMes2)2 (2) was prepared and structurally characterized. Complex 2 reacts with 2 equiv of xylylisocyanide to give the bis-insertion product CpCp*Hf[C(SbMes 2)= N(2,6-MeC6H3)]2 (4). The reaction of 2 with oxidants (I2 and O2) or donors (carbon monoxide and diphenylacetylene) or thermolysis promotes the reductive elimination of Sb2Mes4.

Trimesitylstibane (1) reacts with SbCl3 or SbBr3 to form the halostibanes Mes2SbCl (2), MesSbCl2 (3), Mes2SbBr (4), or MesSbBr2 (5) .Action of MesMgCl on an excess of SbCl3 or SbBr3 at low temperatures gives Mes3SbCl2 (6) or Mes3SbBr2 (7), resp.Addition of Br2 to 1 gives 7 in 96percent yield.The silylstibanes Mes2SbSiMe3 (8) and MesSb(SiMe3)2 (9) are formed by dehalogenation of Me3SiCl and 4 or 5 by Mg filings in tetrahydrofuran.Mes2SbOSiMe3 (10) is obtained by air oxidation of 8.Reduction of 4 with Mg gives Mes2SbSbMes2 (19).Crystals of the composi tion (MesSb)6*C6H6 (13a) or (MesSb)4*C6H5CH3 (13b) are obtained from Mg and 5 after work-up in benzene or toluene, resp. - Keywords: Trimesitylstibane, Halomesitylstibanes, Trimesitylantimonydihalides, Tetramesityldistibane, Hexamesityl-cyclo-hexastibane, Mesityl(trimethylsilyl)stibanes
