Afsharnadery, Fatemeh; Khosravi, Kaveh; Zolfigol, Mohammad Ali published their research in Applied Organometallic Chemistry in 2021. The article was titled 《A novel magnetically recyclable semi-dendrimer catalyst-based ethanolpyridole supported on ferrite nanoparticles (HNPs@Py) for the synthesis of biscoumarin and dihydropyrano[3,2-c]chromene derivatives》.Synthetic Route of C7H9NO The article contains the following contents:
The novel organic-inorganic nanohybrid magnetic nanoparticles (HNPs@Py) were prepared by a simple method and characterized by FT-IR, XRD, FE-SEM, TGA, VSM, EDX, and MAP. The catalytic activity of this new (HNPs@Py) was studied for green synthesis of biscoumarins I (R = 4-Br, 3-NO2, 2-OH, etc.) and 3,4-dihydropyrano[c]chromene derivatives II (Ar = 2,4-dichlorophenyl, naphthalen-2-yl, 3-hydroxyphenyl). The short reaction time, high yields, simple workup, and easy separation of catalyst from the reaction mixture by an external magnetic field are the main advantages of the present protocol. In the experiment, the researchers used 2-(2-Hydroxyethyl)pyridine(cas: 103-74-2Synthetic Route of C7H9NO)
2-(2-Hydroxyethyl)pyridine(cas: 103-74-2) belongs to pyridine. Pyridine’s structure is isoelectronic with that of benzene, but its properties are quite different. Pyridine is completely miscible with water, whereas benzene is only slightly soluble. Like all hydrocarbons, benzene is neutral (in the acid–base sense), but because of its nitrogen atom, pyridine is a weak base.Synthetic Route of C7H9NO
