The oxidation of silanes into silanols is a very necessary transformation, and yet the rational fabrication of efficient catalysts for this reaction remains a challenging task. Here, a 3D polyoxometalate-based metal–organic framework (POMOF), [CuΙ3(pz)3PMo12O40}]·H2O (HENU-8, HENU = Henan University; pz = pyrazine) was consciously prepared and first employed in the oxidation of dimethylphenylsilane
硅烷氧化成硅烷醇是一项非常必要的转化,但合理制备用于该反应的高效催化剂仍然是一项具有挑战性的任务。在这里,有意识地构建了基于 3D 多金属氧酸盐的金属有机骨架 (POMOF) [Cu Ι 3 (pz) 3 PMo 12 O 40 }]·H 2 O ( HENU-8 , HENU = Henan University; pz = pyrazine)制备并首次用于以叔丁基过氧化氢 (TBHP) 作为氧化剂氧化二甲基苯基硅烷,产率为 89%,产率为 132 mmol·g –1 ·h –1. 对照实验表明,多金属氧酸盐和铜原子共同影响该催化体系的最终结果,并且设计的催化剂遵循自由基机制。
