Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 2-Ethylbenzo[d]oxazole, is researched, Molecular C9H9NO, CAS is 6797-13-3, about Synthesis and characterization of amino glucose-functionalized silica-coated NiFe2O4 nanoparticles: A heterogeneous, new and magnetically separable catalyst for the solvent-free synthesis of 2,4,5-trisubstituted imidazoles, benzo[d]imidazoles, benzo[d] oxazoles and azo-linked benzo[d]oxazoles.SDS of cas: 6797-13-3.
Amino glucose-functionalized silica-coated NiFe2O4 nanoparticles (NiFe2O4@SiO2@amino glucose) were chem. synthesized and characterized by transmission electron microscope (TEM), X-ray diffraction (XRD), thermal gravimetric anal. (TGA), energy dispersive X-ray anal. (EDX), vibrating sample magnetometer (VSM), Zetasizer and Fourier transform IR spectroscopy (FT-IR) instruments. NiFe2O4@SiO2@amino glucose supply an environmentally friendly procedure for the synthesis of 2,4,5-trisubstituted imidazoles through one-pot multicomponent condensation of benzil or benzoin, ammonium acetate with aryl aldehydes and for the synthesis of benzoxazoles using condensation reaction of 2-aminophenol with aryl aldehydes under solvent free condition. In the other study, this synthesized magnetically reusable catalyst was introduced as a new avenue for the synthesis of benzo[d]imidazoles using the reaction between aryl aldehydes and 1,2-diaminobenzene. These compounds were obtained in high yields and short reaction times. The catalyst could be easily recovered and reused for five cycles with almost consistent activity. Synthesized compounds were characterized by their phys. constant, comparison with authentic samples, FT-IR, 1H NMR, 13C NMR spectroscopy and elemental anal.
This literature about this compound(6797-13-3)SDS of cas: 6797-13-3has given us a lot of inspiration, and I hope that the research on this compound(2-Ethylbenzo[d]oxazole) can be further advanced. Maybe we can get more compounds in a similar way.
