The lack of effective strategies for direct construction nitrogen–nitrogen bonds has hampered developments in the synthesis and application molecules containing hydrazine or azo motifs. Attracted by their properties both material science medicinal chemistry, more attention been drawn to this area, resulting fast growth design azaheterocycles substituted hydrazines. This review focuses on efficient catalytic approaches toward formation N–N N═N through different strategies, including oxidative dehydrogenation, nitrene-transfer reaction, reductive coupling, some other recently developed methods.

The process of washing and removing crude oil from spent catalysts is a serious issue in both catalyst regeneration precious metals recovery. In this work, five different solvents with various polar aromatic properties were chosen to evaluate their impact on the support structure recovery oil-contaminated catalysts. After deoiling process, was analyzed by scanning electron microscopy, X-ray diffraction (XRD), Fourier transform-infrared spectroscopy, elemental analyzer, contact angle measurement, gas chromatography-mass spectrometry, inductively coupled plasma-atomic emission Brunauer Emmet Teller (BET) method. Our findings demonstrate that p -xylene kerosene are more effective than other solvents. This due oil’s similar polarity molecular nature p- xylene. Considering economical reason, better choice for compared as it affordable -xylene. XRD data show unaltered solvent treatment while BET reveals surface area pore volume significantly enhanced after process. These results imply very crucial step recycling, regeneration, reuse work significant developing sustainable approaches managing catalysts, minimizing waste environmental pollution.

The oxidative formation of N-N bonds from primary amides has been recently reported and then retracted in the journal Nature Communications by Kathiravan, Nicholls, co-authors, utilizing a hypervalent iodane reagent. Unfortunately, authors failed to recognize Curtius reaction taking place under described conditions. Thus, claimed coupling products were not formed. Instead, rearrangement urea obtained. We demonstrate this herein means NMR x-ray analysis, as well with support an alternative synthetic route.
