BHT with tBuONa in solution and in the solid state were examined, reveraling that NaBHT does not need to be prepared from pyrophoric NaH or metallic Na every time. Instead, it can be generated efficiently in or ex situ using NaOtBu in solution or with only a stoichiometric amount of solvent to assist in bringing the reactants together. Application of this methodology was demonstrated with the efficient
Na
BHT 是一种有价值的中等强度基料,可用于许多应用,尤其是 Buchwald-Hartwig 耦合。使用单晶 X 射线衍射建立了无溶剂 Na
BHT 及其与 Et 2 O、THF、t BuOH 和 THF/ t BuOH 混合物的溶剂化物的结构。[Na
BHT·Et 2 O] 2采用二聚体结构并在单斜晶胞中结晶,[Na
BHT·THF] 3、[Na
BHT· t BuOH] 3和[Na
BHT·(THF- t BuOH)] 3更喜欢三聚体结构并在立方晶胞中结晶。无溶剂 [Na
BHT] n不同于溶剂化的 Na
BHT 和其他已知的
苯酚钠。它是一种无机
聚合物,在正交晶胞中结晶,NaO 核沿 [1 0 0] 方向扩展。所有结构都证实了t Bu 基团
氢与 Na 的主动相互作用,可能有助于解释 Na
BHT 的还原特性。此外,研究了
BHT 与t BuONa 在溶液中和固态中的相互作用,表明 Na
BHT 不需要每次都从自燃的
