• Structural insights into mono-amido tris-alkyl potassium aluminates

  Co-complexation of a potassium amide with iBu3Al in the presence of the tridentate chelating ligand PMDETA results in a series of potassium aluminates of general formula [PMDETA·K(μ-amide)(μ-iBu)Al(iBu)2] [where amide = TMP (6); DMP (7); HMDS (8)] which have been characterized by solution NMR spectroscopy and X-ray crystallography. Their solid-state structures contain a central KNAlC ring whose degree of puckering is dictated by the differing interactions between the potassium centre and the aluminium bound anionic ligands.

  在三叉螯合配体 PMDETA 的存在下，钾酰胺与 iBu3Al 发生共络合，产生了一系列通式为 [PMDETA-K(μ-酰胺)(μ-iBu)Al(iBu)2][其中酰胺 = TMP (6)；DMP (7)；HMDS (8)]的铝酸钾，这些铝酸钾已通过溶液核磁共振光谱和 X 射线晶体学进行了表征。它们的固态结构包含一个 KNAlC 中心环，其皱缩程度由钾中心和铝结合阴离子配体之间不同的相互作用决定。

• Tris-pyrazolylborate complexes of redox inactive lanthanides – the structures of [(TpMe2)2NdX] (X=Cl, NPh2, dpm, H2BEt2)

  A range of complexes of Cc and Nd have been prepared to compare the chemistry of the non-reducible [(Tp(Me2))(2)LnX] (Ln = Ce, Nd) with that reported previously for the redox-active samarium ion. The chloride [(Tp(Me2))(2)NdCl] is a useful starting material for the preparation of the seven coordinate [Nd(Tp(Me2))(2)OAr] (Ar=C6H4-4-X; X=H, Bu-t, Br, Ph, OMe, F, Me) and [Nd(Tp(Me2))(2)NPh2]. Crystal structures of [Nd(Tp(Me2))(2)Cl] and [Nd(Tp(Me2))(2)NPh2] are isostructural with those of the analogous samarium, species. The eight coordinate species [Nd(Tp(Me2))(2)(beta-dike)] (beta-dike=(RC=O)(2)CH, R=Me, Ph; Bu-t) and their cerium analogues (R = Ph, Bu-t) have also been prepared. The complexes are fluxional, the extent of this behaviour depending on the steric bulk of the substituents. The structure of [Nd(Tp(Me2))(2)((BuCO)-C-t)(2)CH] has been determined. Finally, in efforts to prepare a neodymium hydride, the unexpected borohydride [Nd(Tp(Me2))(2)(H2BEt2] has been isolated serendipitously and structurally characterized. (C) 2003 Elsevier Ltd.

  Under metalation conditions the 2,4-pentadienylboranes 2,4-C5H7B(NR2)2 (R = Me, Et) and 2,4-C5H7B(O2C2Me4) undergo an electrocyclic ring closure to form borabenzene derivatives. This novel reaction provides a far more efficient access to borabenzene chemistry than previous methods. The dimethylamino derivative [LiMe2N(CH2)3NMe2}](C5H5BNMe2) is the first boratabenzene salt to be structurally characterized.

  Novel yttrium chelating diamide complexes [(YArN(CH2)xNAr}(Z)(THF)n)y] (Z = I, CH(SiMe3)2, CH2Ph, H, N(SiMe3)2, OC6H3-2,6-tBu2-4-Me; x = 2, 3; n = 1 or 2; y = 1 or 2) were made via salt metathesis of the potassium diamides (x = 3 (3), x = 2 (4)) and yttrium triiodide in THF (5, 10), followed by salt metathesis with the appropriate potassium salt (6–9, 11–13, 15) and further reaction with molecular hydrogen (14). 6 and 11 (Z = CH(SiMe3)2, x = 2, 3) underwent unprecedented exchange of yttrium for silicon on reaction with phenylsilane to yield (SiArN(CH2)xNAr}PhH) (x = 2 (16), 3) and (SiCH(SiMe3)2}PhH2).
