The first example of a homogeneous gold(III)-catalysed epoxidation of aromatic alkenes at room temperature using sodium chlorite as the stoichiometric oxidant in a homogeneous trisolvent system of 2-methoxyethanol/acetonitrile/water (volume ratio: 1/3/1) is reported. A radical-trapping experiment suggested that the reaction might proceed via a radical pathway.
efficient and selective epoxidation of alkenes via the design of specialized ligands, which facilitates to control the activity and selectivity of the reactions catalyzed by iron atom. Herein, we report the development of the olefinepoxidation with inorganic-ligand supported iron-catalysts using 30% H2O2 as an oxidant, and the mechanism is similar to iron-porphyrin type. With the catalyst 1, (NH4)3[FeMo6O18(OH)6]
在过去的二十年中,在过渡铁催化的烯烃选择性氧化为环氧化物方面取得了重大进展。在药物,分离的天然产物和精细化学品中发现的常见结构。这些方法中的许多已通过专门配体的设计实现了烯烃的高效和选择性环氧化,这有助于控制铁原子催化的反应的活性和选择性。本文中,我们报道了使用30%H 2 O 2作为氧化剂的无机配体负载的铁催化剂进行烯烃环氧化的研究进展,其机理与铁卟啉类型相似。对于催化剂1,(NH 4)3 [FeMo 6O 18(OH)6 ],各种芳族和脂肪族烯烃均以优异的收率以及化学和立体选择性成功地转化为相应的环氧化物。该催化体系具有能够避免使用昂贵的,有毒的,对空气/湿气敏感的和商业上不可用的有机配体的优点。该方法的通用性易于操作,具有较高的催化活性和优异的稳定性,这使其有可能在工业规模上使用,并可能为通过无机配体配位的铁催化进行催化氧化反应开辟一条道路。。

selectivity and often good yields. The cobaltoxidecatalyst can be recycled up to five times without significant loss of activity or change in structure. Characterization of the catalyst by XRD, TEM, XPS, and EPR analysis revealed the formation of cobaltoxide nanoparticles with varying size (Co3O4 with some CoO) and very few large particles with a metallic Co core and an oxidic shell. During the pyrolysis process
芳香族和脂肪族烯烃的一般环氧化反应是在温和条件下使用多相Co x O y -N / C(x = 1,3; y = 1,4)催化剂和叔丁基氢过氧化物作为末端氧化剂而开发的。包括可再生烯烃,维生素和胆固醇衍生物在内的各种斯蒂芬酯和脂肪族烯烃已成功地以高选择性和高收率成功地转化为相应的环氧化物。氧化钴催化剂可以循环使用多达五次,而不会显着降低活性或改变结构。通过XRD,TEM,XPS和EPR分析对催化剂进行表征,发现形成了大小各异的氧化钴纳米颗粒(Co 3 O4含一些CoO),几乎没有带有金属Co核和氧化壳的大颗粒。在热解过程中,氮配体形成石墨烯型层,其中选定的碳原子被氮取代。
