Synthetic Route of C9H9NO. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 2-Ethylbenzo[d]oxazole, is researched, Molecular C9H9NO, CAS is 6797-13-3, about Site-Selective and Stereoselective C(sp3)-H Borylation of Alkyl Side Chains of 1,3-Azoles with a Silica-Supported Monophosphine-Iridium Catalyst. Author is Murakami, Ryo; Iwai, Tomohiro; Sawamura, Masaya.
Site-selective and stereoselective C(sp3)-H borylation of alkyl side chains of 1,3-azoles with bis(pinacolato)diboron was effectively catalyzed by a silica-supported monophosphine-iridium catalyst. The borylation occurred under relatively mild conditions (2 mol% Ir, 50-90°), affording the corresponding primary and secondary alkylboronates. This system was applicable to a variety of 1,3-(benzo)azoles such as thiazoles, oxazoles, and imidazoles.
As far as I know, this compound(6797-13-3)Synthetic Route of C9H9NO can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
