• Syntheses and X-ray structures of boraamidinate complexes of lithium, phosphorus, and tellurium

  The dilithiated boraamidinate complexes Li₂[RB(N-t-Bu)₂]}₂ (1a, R = Ph; 1b, R = t-Bu), prepared by the reaction of B[N(H)-t-Bu]₃ with three equivalents of LiR, are shown by X-ray crystallography to have dimeric structures consisting of a distorted Li₄N₄ cube capped on two opposite faces by RB units. Reactions of 1a with TeCl₄ or PX₃ (X = Cl, Br) yielded complexes PhB(μ-N-t-Bu)₂TeCl₂ (2) and PhB(μ-N-t-Bu)₂PX (4a, X = Cl; 4b, X = Br), respectively. The structures of 2 and 4b were determined by X-ray crystallography. In the solid state, complex 2 forms a dimer with weak Te···Cl contacts (3.2411(6) Å). Complex 4b is monomeric with a P—Br bond length of 2.3047(11) Å. The reactions of 2 and 4a with the appropriate amounts of Li[N(H)-t-Bu] produce the monomeric tellurium imide PhB(μ-N-t-Bu)₂Te=N-t-Bu and the amido derivative PhB(μ-N-t-Bu)₂PN(H)-t-Bu (4c), respectively. The X-ray structure of 4c was determined. Deprotonation of 4c with n-BuLi produces the dimeric monolithium derivative Li[PhB(μ-N-t-Bu)₂PN-t-Bu]}₂ (5), which was shown by X-ray crystallography to have a centrosymmetric structure with a central transoid Li₂N₂ ring.Key words: boraamidinates, lithium, tellurium, phosphorus, X-ray structures.

  The products of the reaction between tris(primary amino)boranes and boron trifluoride have been shown to depend on the nature of the alkyl group present. When R = Pri or But the product is the primary aminoboron difluoride dimer, (RNHBF2)2, whereas when R = Me, Et, Prn, or Bui the product is the corresponding primary amine–boron trifluoride adduct together with various substituted borazines. Likewise

  A new general synthesis of β-keto-enolates is described, whereby diketen is caused to react with various organic derivatives of aluminium, boron, and tin. Diketen thus reacts differently from its monomer (which affords C-acetyl derivatives). This is attributed to the unsymmetrical structure of the dimer. The symmetrical phenyl isocyanate dimer behaves similarly to its monomer in its reaction with

  描述了β-酮-烯酸酯的新的一般合成，由此使二烯酮与铝，硼和锡的各种有机衍生物反应。因此，二烯酮的反应与其单体（产生C-乙酰基衍生物）的反应不同。这归因于二聚体的不对称结构。对称的异氰酸苯基酯二聚物在与三二甲基氨基硼烷反应中的行为与其单体相似。β-酮-烯酸酯的特征在于元素分析，分子量，光谱数据（ir，uv，nmr和质谱），在某些情况下，其特征在于化学降解或合成的替代方法。
