Ultrasonically activated reduction of substituted nitrobenzenes to corresponding N-arylhydroxylamines

Arylhydroxylamines can be obtained by reduction of the corresponding nitroaromatic compounds. We report here an efficient preparation of arylhydroxylamines by a controlled reduction of nitro compounds using zinc metal and ammonium chloride under ultrasonic activation in very short reaction times.

Palladium Supported on Carbon Nanoglobules as a Promising Catalyst for Selective Hydrogenation of Nitroarenes

The catalysts 1?wt% palladium supported on carbon nanoglobules (CNGs) were shown to be highly active in the liquid-phase hydrogenation of various nitroarenes and provided nearly 100% selectivity to aromatic amines at complete conversion under mild conditions (323?K, 0.5?MPa, 1?h). The catalytic activity (in terms of turnover frequency and substrate conversion) and selectivity depend on the kind of CNGs support, catalyst preparation method and the reaction conditions (solvent nature). The Pd/CNGs catalyst can be repeatedly used while maintaining the same catalytic performance. The excellent performances of Pd/CNGs catalysts can be due to the globular morphology of the supports as well as the absence of micropores and pronounced surface defects.

Rhodium(III)-catalyzed internal oxidative coupling of N-hydroxyanilides with alkenes via C-H activation

Abstract Described herein is an efficient new method for ortho-olefination of anilides in the presence of AgSbF6 and NaOAc via rhodium(III)-catalyzed internal oxidative C-H bond activation based on hydroxyl as directing and oxidative group. A range of alkenes and functional groups on acetanilides is supported and a possible mechanism is proposed according to the experimental results.

Synthesis of N-arylhydroxylamines by Pd-catalyzed coupling

Pd-catalyzed coupling of aryl halides with TeocNHOTBS, followed by treatment of the products with TBAF, provides effective access to a wide range of N-arylhydroxylamines by a route that produces stable doubly-protected intermediates and allows the protective groups to be removed under mild conditions that do not cause extensive degradation of the final product.

Ultrasound-promoted highly chemoselective reduction of aromatic nitro compounds to the corresponding N-arylhydroxylamines using zinc and HCOONH 4 in CH3CN

N-Arylhydroxylamines were prepared in high yields through chemoselective reduction of the corresponding aromatic nitro compounds under ultrasound (59 kHz) at room temperature using a convenient Zn/HCOONH4/CH 3CN system. This method was highly efficient, environmentally benign, especially simple and practical. Copyright

Mechanism and reactivity in perborate oxidation of anilines in acetic acid

Perborate but not percarbonate in acetic acid generates peracetic acid on standing and the peracetic acid oxidation of anilines is fast. The oxidation with a fresh solution of perborate in acetic acid is smooth and second order but the specific oxidation rate increases with increasing [perborate]0 or [boric acid]. Perborate on dissolution affords hydrogen peroxide and a borate; the latter assists the former in the oxidation. The oxidation rates of anilines under identical conditions do not conform to any of the linear free energy relationships but the reaction rates of molecular anilines do. Perborate oxidation proceeds via two reaction paths but the overall oxidation rates of molecular anilines conform to structure reactivity relationships; the transition states do not differ significantly. Analysis of the oxidation rates of perborate and percarbonate reveals that while perborate oxidation is faster than percarbonate it is at least as selective as the latter.

Kinetics and Mechanism of Oxidation of para-Substituted Anilines by Peroxomonosulphate

Kinetics of oxidation of several para-substituted anilines by peroxomonosulphate (PMS) in aqueous acetic acid medium have been investigated. The reaction follows a total second order, first order each in [PMS] and [substrate]. The reaction rate is retarted by both electron-releasing and withdrawing groups. Absence of free radical formation is confirmed. Activation energy and thermodynamic parameters have been computed. A probable mechanism has been proposed.
