Tungstate ions (WO4=) supported on imidazolium framework as novel and recyclable catalyst for rapid and selective oxidation of benzyl alcohols in the presence of hydrogen peroxide was written by Hosseini Eshbala, Fereshteh;Mohanazadeh, Farajollah;Sedrpoushan, Alireza. And the article was included in Applied Organometallic Chemistry in 2017.Application of 21252-69-7 This article mentions the following:
A tungstate salt with an imidazolium framework is found to be a recoverable and heterogeneous system favoring the highly selective oxidation of primary benzylic alcs. to corresponding aldehydes with 30% H2O2 as a green oxidant under neutral aqueous reaction conditions. Furthermore, in order to demonstrate the recyclability of the catalyst, it was recovered and efficiently reused in seven succeeding reaction cycles without any significant loss. The use of green solvent, very short reaction time with excellent yields, and recyclability of the catalyst make this protocol highly advantageous. In the experiment, the researchers used many compounds, for example, 1-Octyl-1H-imidazole (cas: 21252-69-7Application of 21252-69-7).
1-Octyl-1H-imidazole (cas: 21252-69-7) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Application of 21252-69-7
