  Catalytic Dealkylation of Phosphates with Binuclear Boron Compounds

  摘要：

  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.

  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。
