Abdallah, Sanaa O.,Metwally, Nadia H.,Anwar, Hany F.,Elnagdi, Mohamed H.
, p. 781 - 786 (2005)
2-Formyl-2-arylhydrazonoethanenitriles 6b-d where prepared via reacting enaminonitrile 2b,c with aromatic diazonium salts. These reacted with phenylhydrazine to yield bis hydrazones that were converted to arylazopyrazoles via a novel Vilsmeier-Haack reaction type. Reaction of 6c with hydroxylamine afforded oxime that could be successfully cyclised into arylazoisoxazole. Reaction of 6c with hydrazine hydrate to yield arylazoaminopyrazole that proved to be excellent precursors for synthesis functional substituted pyrazolopyrimidines.
Synthesis and liquid crystalline properties of a disc-shaped molecule with azobenzene at the periphery
Rahman, Md. Lutfor,Tschierske, Carsten,Yusoff, Mashitah,Silong, Sidik
, p. 2303 - 2306 (2005)
A triphenylene-based novel liquid crystal was synthesised whose peripheral cores are six rod-like azobenzene moieties linked through alkyl chains. A disc-shaped molecule 2,3,6,7,10,11-hexakis-[{4-(4-nitrophenylazo)phenoxy} hexyloxy]triphenylene was prepar
Synthesis of an electron-rich aniline-containing dye and its dyeing behaviors on silk through a three-component Mannich-type reaction

Under the guidance of the finding that the tyrosine residues in proteins could undergo three-component Mannich-type reactions with formaldehyde and electron-rich aniline-containing compounds, which forms covalent bonding connections between the protein of
Synthesis and characterization for new Zn(II) complexes and their optimizing fertilization performance in planting corn hybrid
Althagafi, Ismail,Morad, Moataz,Al-dawood, Aisha Y.,Yarkandy, Naema,Katouah, Hanadi A.,Hossan, Aisha S.,Khedr, Abdalla M.,El-Metwaly, Nashwa M.,Ibraheem, Farag
, p. 2121 - 2133 (2021)
Novel Zn(II)–benzohydrazide complexes have been synthesized using Zn(NO3)2·6H2O salt. All new synthesises were investigated by available analytical and spectral tools to demonstrate their formulae. Binuclear complexes were
Synthesis and characterization of new pyrazole-based thiazoles
Abdelhamid, Abdou O.,Gomha, Sobhi M.
, p. 1409 - 1414 (2017)
A series of new 5-(heteroaryldiazenyl)thiazole incorporating pyrazole moiety have been synthesized through coupling of the thiazole with the appropriate heteroaryldiazonium salts. The newly synthesized compounds were characterized by elemental analysis, s
Synthesis and crystal structure of 1-methyl-3-(4-nitrophenyl)-1,2,3 triazolium perchlorate
Doreswamy,Mahendra,Sridhar,Prasad, J. Shashidhara,Mantelingu,Basappa,Rangappa
, p. 67 - 75 (2003)
The isolation of stable carbenes of the Arduengo (1a) and Wanzlick (2a) type has prompted us to look for stable nitrenium ions of the related structural type 1-melhyl-3-(4-nitrophenyl)-1,2,3 triazolium perchlorate (6). The title compound (C9 H
N-acyl triazenes as tunable and selective chemodosimeters toward cyanide ion
Chung, Yunmi,Lee, Hanna,Kyo, Han Ahn
, p. 9470 - 9474 (2006)
(Figure Presented) A novel type of chemodosimeters has been developed on the basis of a displacement reaction. N-Acyl-triazenes are found to be highly selective and tunable chemodosimeters toward cyanide. When N-acetyl-triazene 1a was titrated with variou
Fluoride-responsive organogel containing azobenzyl and cholesterol units
Geng, Lijun,Feng, Guoliang,Wang, Shiguang,Yu, Xudong,Xu, Zhice,Zhen, Xiaoli,Wang, Tao
, p. 24 - 28 (2015)
In this paper, two new cholesterol-based compounds O1 and O2 were designed and synthesized. The compound O2 could selectively gel in 1,4-dioxane with porous ribbon structure. The aggregation mode of O2 molecules were characterized by SEM, IR, UV-vis and X
