Aqueous hydrogenperoxide is widely used as an oxidizingagent in industry and academia. Herein, the hydrogenperoxide 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
过氧化氢水溶液在工业和学术界广泛用作氧化剂。在此,对氧化膦[ t Bu 3 PO · H 2 O 2 ] 2和[Ph 3 PO · H 2 O 2 ] 2 · H 2 O 2的过氧化氢加成物进行说明。另外,相应的二(氢过氧)丙烷加合物[R 3 PO ⋅(HOO)2 CME 2(R = Cy,Ph)被合成并表征。所有加合物都可以作为大型单晶获得,适合通过X射线晶体学和固态NMR光谱进行结构表征。二(氢过氧)丙烷加合物可溶于有机溶剂中,从而能够在一相中进行氧化反应。由于加合物是固体和分子,因此可以很容易地以化学计量方式应用。将单晶在室温下长期保存或将粉末在-20°C下保存时,不会发生氧化力损失的情况。

free water that interacts with 1 after photochemical dissociation of CO (1-CO) constituting the oxidative half-reaction of water splitting mediated by 1. Hydrogen production from 1 is the result of several different processes, one of which involves the protons derived from the hydroxido ligands in 1 constituting the reductive half-reaction of water splitting mediated by 1. Other processes that generate
与水衍生的配体,如公知的[锰(CO)某些有机金属发色团3(μ 3 -OH)] 4(1)的四聚体,把我们的注意力尽可能平台研究水分解反应。在本文中,我们研究了包括1在内的各种三羰基有机锰配合物的紫外线辐射,并证明在光化学水分解分解反应中,二氢,一氧化碳和过氧化氢作为产物形成。还对有机和含锰副产物进行了表征。18 O-1的标记研究表明,H 2 O 2中的氧原子来源源于游离水,该游离水在CO(1-CO)光化学解离后与1相互作用,从而构成由1介导的水分解的氧化半反应。从1制氢是几种不同过程的结果,其中之一涉及1中的羟基配体衍生的质子,构成1介导的水分解的还原半反应。产生H 2的其他过程也是可操作的,并进行了描述。1的光化学分解的结果 提供了提出机制的机会,并在开发与有机锰配合物进行水分解反应的新策略的背景下进行了讨论。

spectra of 1 : 1 triphenylphosphine oxide adducts of [MN(SiMe3)2}3](M = La Eu, or Lu) and dimeric peroxo-species [M2N(SiMe3)2}4(O2)(PPh3O)2](M = La, Pr, Sm, Eu, or Lu) are described. The crystal and molecular structures of [LaN(SiMe3)2}3(PPh3O)](1) and [La2N(SiMe3)2}4(O2)(PPh3O)2](2) have been determined bysingle-crystal X-ray diffraction methods from data measured on a manual diffractometer and refined
