• Boron halide chelate compounds and their activity towards the demethylation of trimethylphosphate

  Salen(t-Bu)H₂ (N,N'-ethylenebis(3,5-di-tert-butyl(2-hydroxy)benzylidenimine) and its derivatives were used to prepare boron compounds having the formula L(BCl₂)₂ (L = salen(t-Bu) (1), salpen(t-Bu) (2), salben(t-Bu) (3), salpten(t-Bu) (4), salhen(t-Bu) (5)). These are formed from the reaction of the corresponding L[B(OMe)₂]₂ with BCl₃. In addition to being a new type of boron compound, they are also potential two-point Lewis acids. Indeed, they demonstrate Lewis acidic behavior in the dealkylation of trimethylphosphate. All of the compounds were characterized by mp, elemental analysis, ¹H and ¹¹B NMR, IR, MS, and in the case of 2 by X-ray crystallography.Key words: boron, salen, dealkylation.

  Salen(t-Bu)H2（N，N'-乙烯基双（3,5-二叔丁基（2-羟基）苯基亚甲基）和其衍生物被用于制备具有L（BCl2）2（L = salen（t-Bu）（1），salpen（t-Bu）（2），salben（t-Bu）（3），salpten（t-Bu））的硼化合物。 （4），salhen（t-Bu）（5））。这些化合物是通过相应的L [B（OMe）2] 2与BCl3反应形成的。除了是一种新型的硼化合物外，它们还具有潜在的双点路易斯酸性。实际上，它们在三甲基磷酸酯的脱烷基化反应中表现出路易斯酸性行为。所有化合物都通过mp，元素分析，1H和11B NMR，IR，MS以及2的X射线晶体学进行了表征。关键词：硼，salen，脱烷基化。

  日期：2002.3.1

  The Salen(tBu) ligand and its derivatives were used to prepare binuclear boron complexes. These compounds have the formula, L(BBr2)2 (L = Salpen(tBu) and Salben(tBu)). These are formed from the reaction of the corresponding L[B(OMe)2]2 with BBr3. They represent a new type of binuclear boron compound. These compounds are active towards the dealkylation of many phosphates. They are also catalytically active with a stoichiometric amount of BBr3 to trimethylphosphate.

  The ligand N,N"-bis(2-hydroxybenzylidene)diethylenetriamine (SalenN(3)H(3)) was used to prepare the compound SalenN(3)HB(OMe2)}(2) (1) which could, in turn, be used in the formation of SalenN(3)HB(OSiPh3)(2)}(2) (2). For comparative purposes, the compounds SalbenB(OSiPh3)(2)}(2) (3) (Salben = N,N'-butylenebis(2-hydroxybenzylideneamine), Salen(Bu-t)B(OSiPh3)(2)}(2) (4) (Salen(Bu-t) = N,N'-ethylenebis(3,5-di-tert-butyl-2-hydroxy-benzylideneamine) and Salben(Bu-t)B(OSiPh3)(2)}(2) (5) (Salben(Bu-t) = N,N'-butylenebis(3,5-di-tert-butyl-2-hydroxybenzylideneamine) were prepared. In reactions where the siloxide is (HO)(2)SiPh2, unique dimeric siloxide-bridged compounds result, [Salpten(Bu-t)B(O2SiPh2}](2) (6) and [SalenN(3)HB(O2SiPh2)}](2) (7). Compound 6 possesses a zeolite-like cavity having a volume of 157 Angstrom(3). All Of the compounds were characterized by physical (mp, analyses) and spectroscopic techniques (H-1 and B-11 NMR, IR) and, in the case of 1, 3, 4, and 6, by X-ray crystallography.
