Chemical Research Letters, May 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. , SDS of cas: 620-92-8, 620-92-8, Name is 4,4′-Methylenediphenol, molecular formula is C13H12O2, belongs to naphthyridine compound. In a document, author is Refat, Hala M., introduce the new discover.
New 3-aryl-pyrido[2,1-b][1,3] benzothiazole derivatives 2a-e were synthesized in excellent yields via the reaction of benzothiazoleacetonitrile (1) with different aromatic aldehydes. The treatment of 2-(benzo[d] thiazol-2-yl)-3-(pyridin-4-yl) acrylonitrile (6) with malononitrile afforded 1-amino-3-(pyridin-4-yl)-3H-pyrido[2,1-b][1,3] benzothiazole-2,4-dicarbonitrile (7), which was allowed to react with a variety of reagents to provide pyrimido[5′, 4′: 5,6] pyrido[2,1-b][1,3] benzothiazole 8, 9 and [1,3] benzothiazolo[3,2-a][1,8] naphthyridine 10, 15 derivatives. All synthesized products were confirmed by elemental analysis, IR, H-1-NMR, C-13-NMR, and mass spectral data.
The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states. I hope my blog about 620-92-8 is helpful to your research. SDS of cas: 620-92-8.
