Awesome Chemistry Experiments For 620-92-8

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 620-92-8 help many people in the next few years. Application In Synthesis of 4,4′-Methylenediphenol.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 620-92-8, Name is 4,4′-Methylenediphenol, formurla is C13H12O2. In a document, author is Refat, Hala M., introducing its new discovery. Application In Synthesis of 4,4′-Methylenediphenol.

Efficient and convenient synthesis of pyrido [2,1-b]benzothiazole, pyrimidopyrido[2,1-b]benzothiazole and benzothiazolo[3,2-a][1,8]naphthyridine derivatives

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.
