چکیده
Catalytic synthesis of aromatic azo compounds by oxidative coupling anilines using molecular oxygen represents a facile, green and valuable process; however, such an economical process suffers from poor catalytic activity selectivity.

Gold-catalyzed direct hydrogenative coupling of nitroarenes to synthesize aromatic azo compounds.
The azo linkage is a prominent chemical motif which has found numerous applications in materials science, pharmaceuticals, and agrochemicals. Described herein is a sustainable heterogeneous-gold-catalyzed synthesis of azo arenes. Available nitroarenes are deoxygenated and linked selectively by the formation of N=N bonds using molecular H2 without any external additives. As a result of a unique ...
متن کاملSolubilization of single-walled carbon nanotubes with condensed aromatic compounds
The results of complex investigations of the crystalline structure, composition and specific magnetization of the multi-wall carbon nanotubes (CNTs) filled by magnetic nanocomposite are performed. CNT arrays have been synthesized by the high temperature pyrolysis of fluid hydrocarbon p-xylole [ 8 10] in the presence of volatile catalyst ferrocene [Fe(C5H5)2] at the walls of tubular-type quartz ...
متن کاملRapid chemoselective bioconjugation through oxidative coupling of anilines and aminophenols.
A highly efficient protein bioconjugation method is described involving addition of anilines to o-aminophenols in the presence of sodium periodate. The reaction takes place in aqueous buffer at pH 6.5 and can reach high conversion in 2-5 min. The major product was characterized using X-ray crystallography, which revealed that an unprecedented oxidative ring contraction occurs after the coupling...
متن کاملSynthesis of azobenzenes: the coloured pieces of molecular materials.
Azobenzenes are ubiquitous motifs very important in many areas of science. Azo compounds display crucial properties for important applications, mainly for the chemical industry. Because of their discovery, the main application of aromatic azo compounds has been their use as dyes. These compounds are excellent candidates to function as molecular switches because of their efficient cis-trans isom...
متن کاملPeptoid nanotubes: an oligomer macrocycle that reversibly sequesters water via single-crystal-to-single-crystal transformations.
A highly thermostable peptoid cyclo-octamer can reversibly accommodate and release water molecules from central channels formed by the macrocycles in a crystalline array. We report the first single-crystal-to-single-crystal transformation for a peptidomimetic oligomer.
