New discoveries in chemical research and development in 2021. As an important bridge between the micro, chemistry is one of the main methods and means for humans to understand and transform the material world. In an article, author is Behzadi, Masoumeh, once mentioned the application of 540-36-3, Category: benzoxazole, category is benzoxazole. Now introduce a scientific discovery about this category.
Graphene oxide (GO) was chemically modified with para-aminobenzoic acid (PABA) to immobilize copper(ii) ions on its surface and used as a nanocatalyst for the oxidative C(sp(2))-H bond amination reaction. A practical method to prepare Cu2+ supported on para-aminobenzoic acid grafted on GO was reported. The prepared Cu2+@GO/PABA was characterized by FT-IR, XRD, SEM, AFM, TEM, UV-Vis, and ICP techniques. The results showed that the morphology, distribution, and loading of copper ions could be well-adjusted by grafting of PABA on GO. Moreover, just 2 mol% of Cu2+@GO-PABA could catalyze the C-H activation reaction of benzoxazole and benzothiazole with secondary amines in >94% yields. Also, the catalyst showed very good recyclability and much less leaching of the Cu into the reaction solution. The high activity of Cu2+@GO-PABA can be ascribed to the good synergistic effects of Cu2+ and para-aminobenzoic acid grafted on graphene oxide.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 540-36-3. The above is the message from the blog manager. Category: benzoxazole.
