phthalimides using catalytic iron/tert-butylhydroperoxide (TBHP) reagent systems is detailed. The 2-substituted-3-hydroxyisoindolin-1-one (hydroxylactam) to imide oxidation constitutes a rather straightforward hydroxyl → carbonyl group conversion while the latter process is a methylene → carbonyl transformation. The iron oxidant Fe (TFA)3 (10 mol%), prepared by the treatment of iron (III) chloride with trifluoroacetic

With demands placed on batteries constantly increasing, new positive electrode materials with higher energy density, satisfactory power density, and long-term cycling capabilities, composed of highly abundant elements with low-cost, are desired. One such low-cost cathodic material is iron(III) fluoride – FeF3. Its theoretical capacity for single-electron reduction, accompanied by the insertion of Li+
随着对电池的需求不断增加,期望具有高能量密度,令人满意的功率密度和长期循环能力的新型正极材料,其由高度丰富的元素组成且成本低廉。一种这样的低成本阴极材料是氟化铁(III)– FeF 3。其理论容量为单电子还原,伴随着锂的插入+离子,是237毫安汞柱-1。在这里,我们提出了一种使用廉价的三氟乙酸铁作为分子单源前体的纳米晶FeF 3的新合成方法。我们还报告了这种简单化学对几种过渡金属二氟化物(M = Fe,Co和Mn)的适应性。含FeF 3,在100 mA g -1(〜0.5 C)的中等电流密度下可获得220 mA hg -1的高容量。除了高容量,我们还看到了高速率容量的证据。在1分钟(10 A g -1)的充放电斜率下,观察到的容量高达155 mA hg -1,并且在100次循环后至少保留了88%的容量。当作为钠阴极进行测试时,FeF 3在200 mA hg -1的电流速率下显示出高达160

A range of tetrahydropyrans and piperidines were produced by Fe(III)-catalyzed intramolecular hydroalkoxylation and hydroamination reactions of allenes. Various Fe catalysts with different counterions were tested. Their activities toward allene and alkene activation depended sensitively on their counterion and reaction conditions. Mechanistic study of the reaction intermediates found a new reaction pattern involving the Fe catalysts and diene substrates.

Iron(III) trifluoroacetate was used as an efficient and nonhygroscopic catalyst for the alcoholysis, hydrolysis, and acetolysis of epoxides. The addition of chloride, bromide, iodide, and nitrate ions to epoxides to produce the corresponding 2-halo and 2-nitratoalkanols and also the conversion of epoxides to acetonides and thiiranes were also performed efficiently in the presence of this catalyst.
