Aqueous hydrogen peroxide is widely used as an oxidizing agent in industry and academia. Herein, the hydrogen peroxide adducts of phosphine oxides, [tBu3PO⋅H2O2]2 and [Ph3PO⋅H2O2]2⋅H2O2, are described. Additionally, the corresponding di(hydroperoxy)propane adducts R3PO⋅(HOO)2CMe2 (R=Cy, Ph) were synthesized and characterized. All adducts could be obtained as large single crystals suitable for structural characterization by X-ray crystallography and solid-state NMR spectroscopy. The di(hydroperoxy)propane adducts are soluble in organic solvents which enables oxidation reactions in one phase. As the adducts are solid and molecular, they can easily be applied stoichiometrically. No loss of oxidizing power occurs upon long-term storage of the single crystals at room temperature or the powders at -20 °C.
过氧化氢水溶液在工业和学术界中被广泛用作氧化剂。在此，我们描述了氧化膦的过氧化氢加合物 [tBu3PO⋅H2O2]2 和 [Ph3PO⋅H2O2]2⋅H2O2，此外，还合成并表征了相应的二（过氧）丙烷加合物 R3PO⋅(HOO)2CMe2（R=Cy，Ph）。所有加合物都可以通过 X 射线晶体学和固态 NMR 光谱法获得适合结构表征的大单晶。二（过氧）丙烷加合物可溶于有机溶剂，可在单相中进行氧化反应。由于加合物是固体和分子的，因此可以很容易地按化学计量使用。这些单晶在室温下或粉末在-20°C 下长期储存时，不会损失氧化能力。
