Ruthenium silicate (RS-1) zeolite: novel heterogeneous efficient catalyst for synthesis of 2-arylbenzothiazole derivatives was written by Gadekar, Sachin P.;Lande, Machhindra K.. And the article was included in Research on Chemical Intermediates in 2021.Recommanded Product: 2-(4-Methylphenyl)benzothiazole This article mentions the following:
Mesoporous silicate and transition metal (Ru+3) containing mesoporous silicate materials or ruthenium silicate Ru+3/Si+4 where synthesis by using hydrothermal process. Mesoporous ruthenium silicate (RS-1) and zeolite catalyst have been successfully synthesized with variable molar ratio such as (a) Ru:Si 1:100, (b) Ru:Si 1:150, (c) Ru:Si 1:200. The elemental composition, structural morphol., crystal phase and properties and various parameters of the catalyst were examined by Fourier transform IR spectroscopy, SEM, powder X-ray diffraction. Energy dispersive X-ray pattern/spectroscopy anal. EDX/EDS, where as the activity of obtained catalysts was tested in the Willgerodt-Kindler synthesis between 2-aminothiophenol and substituted aryl aldehyde (1:1 mol) to form a 2-arylbenzothiazole. The novelty of the presented work was the ruthenium (Ru+3) metal impregnations in silicate framework for the synthesis of novel ruthenium silicate (RS-1) zeolite as a catalyst and the investigation of the various parameters, role, its stability and catalytic activity in the Willgerodt-Kindler (combined both Knovenagel and Maichel addition reaction) synthesis. The developed protocol has several benefits such as short reaction time, mild reaction condition, and good reusability of catalyst. Graphic abstract: [graphic not available: see fulltext]. In the experiment, the researchers used many compounds, for example, 2-(4-Methylphenyl)benzothiazole (cas: 16112-21-3Recommanded Product: 2-(4-Methylphenyl)benzothiazole).
2-(4-Methylphenyl)benzothiazole (cas: 16112-21-3) belongs to thiazole derivatives. Thiazole is a five-membered, unsaturated, planar, π-excessive heteroaromatic containing one sulfur atom and one pyridine-type nitrogen atom at position 3 of the cyclic ring system. Electrophilic attack at nitrogen depends on the presence of electron density at nitrogen as well as the position and nature of substituent linked to the thiazole ring.Recommanded Product: 2-(4-Methylphenyl)benzothiazole
