A cyanide triggered hydrogen bonds breakage deprotonation mechanism: fluorescent detection of CN– using a thioacetohydrazone functionalized bispillar[5]arene

10-Jan-2018 | Tai-Bao Wei; Jin-Dong Ding; Jin-Fa Chen; Bing-Bing Han; Xiao-Mei Jiang; Hong Yao; You-Ming Zhang; Qi Lin, New Journal of Chemistry, 2018

A novel sensor (AHP5) involving a thioacetohydrazone bridged bispillar[5]arene was developed and demonstrated to fluorescently sense CN–. It manifested specificity response for cyanide over other common anions (SCN–, AcO–, HSO4–, H2PO4–, I–, Br–, ClO4–, Cl– and F–) in DMSO/H2O (9 : 1, v/v) ...

A cyanide-triggered hydrogen-bond-breaking deprotonation mechanism: fluorescent detection of cyanide using a thioacetohydrazone-functionalized bispillar[5]arene

29-Dec-2017 | Tai-Bao Wei; Jin-Dong Ding; Jin-Fa Chen; Bing-Bing Han; Xiao-Mei Jiang; Hong Yao; You-Ming Zhang; Qi Lin, New Journal of Chemistry, 2017

A novel sensor (AHP5) comprising a thioacetohydrazone-bridged bispillar[5]arene was developed and shown to fluorescently sense cyanide ions. The sensor manifested a response specific to cyanide over other common anions (SCN−, AcO−, HSO4−, H2PO4−, I−, Br−, ClO4−, Cl−, and F−) in DMSO/H2O (9 : 1, ...

Synthesis of imidazole-activated ribonucleotides using cyanogen chloride

29-Dec-2017 | Ruiqin Yi; Yayoi Hongo; Albert C. Fahrenbach, Chemical Communication, 2017

We report the syntheses of ribonucleoside 5′-monophosphates activated with imidazole, using a mechanism which relies on the in situ generation of cyanogen chloride from the reaction of cyanide anion with hypochlorous acid. Cyanogen chloride reacts rapidly with imidazole to form diimidazole imine ...

Magnetically separable g‐C3N4 hybrid nanocomposite: Highly efficient and eco‐friendly recyclable catalyst for one‐pot synthesis of α‐aminonitriles

22-Dec-2017 | Najmedin Azizi, Elham Farhadi, Applied Organometallic Chemistry, 2017

A magnetically separable graphitic carbon nitride nanocomposite (Fe3O4/g‐C3N4) as a catalyst for the three‐component condensation reactions of carbonyl compounds, amines and trimethylsilylcyanide was thoroughly investigated. The reaction of these three components was found to be efficient, ...

Synthesis of Dicyanovinyl-Substituted 1-(2-Pyridyl)pyrazoles: Design of a Fluorescent Chemosensor for Selective Recognition of Cyanide

05-Dec-2017 | Jessica Orrego-Hernández; Jaime Portilla, The Journal of Organic Chemistry, 2017

A fluorescence “turn-off” probe has been designed and successfully applied to detect cyanide (CN–) based on a Michael-type nucleophilic addition reaction and intramolecular charge transfer (ICT) mechanism. For this research, a family of 3-aryl-4-(2,2-dicyanovinyl)-1-(2-pyridinyl)pyrazoles as ...
