《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. Recommanded Product: 2969-81-5This research focused onunsym ketone preparation; vinyl azide alkyl bromide Vitamin B12 catalyst light irradiation. The article conveys some information:
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 experimental materials used by the author, we found Ethyl 4-bromobutyrate(cas: 2969-81-5Recommanded Product: 2969-81-5)
Ethyl 4-bromobutyrate(cas: 2969-81-5) belongs to bromides. One prominent application of synthetic organobromine compounds is the use of polybrominated diphenyl ethers as fire-retardants, and in fact fire-retardant manufacture is currently the major industrial use of the element bromine.Recommanded Product: 2969-81-5
