Vinyl Azides as Radical Acceptors in the Vitamin B12-Catalyzed Synthesis of Unsymmetrical Ketones was written by Dworakowski, Krzysztof R.;Pisarek, Sabina;Hassan, Sidra;Gryko, Dorota. And the article was included in Organic Letters in 2021.HPLC of Formula: 57293-19-3 This article mentions the following:
Vitamin B12 catalyzed the reaction of vinyl azides with electrophiles under light irradiation to afforded unsym. carbonyl compounds R1C(O)CH2R2 [R1 = Ph, 4-t-BuC6H4, 4-ClC6H4, etc.; R2 = (CH2)3CN, (CH2)3Ph, (CH2)3C(O)OEt, etc.] in decent yields. Mechanistic studies revealed that alkyl radicals were key intermediates in this transformation. In the experiment, the researchers used many compounds, for example, 1-(3-Bromopropyl)-4-methoxybenzene (cas: 57293-19-3HPLC of Formula: 57293-19-3).
1-(3-Bromopropyl)-4-methoxybenzene (cas: 57293-19-3) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. alpha-Bromoesters are employed in the Reformatsky reaction for the synthesis of beta-hydroxyesters. Commercially available organobromine pharmaceuticals include the vasodilator nicergoline, the sedative brotizolam, the anticancer agent pipobroman, and the antiseptic merbromin.
