Electric Literature of C6H4BBrF3KOn May 1, 2020 ,《Deacetylative Aryl Migration of Diaryliodonium Salts with C(sp2)-N Bond Formation toward ortho-Iodo N-Aryl Sulfonamides》 appeared in Organic Letters. The author of the article were Chen, Huangguan; Wang, Limin; Han, Jianwei. The article conveys some information:
An unprecedented approach of metal-free C(sp2)-N bond formation via deacetylation/intramol. aryl migration is demonstrated with novel N-sulfonamide substituted diaryliodonium salts. The reaction provides a variety of ortho-iodo N-aryl sulfonamides. The products were employed in several coupling reactions to afford useful diarylamine scaffolds. Furthermore, the key intermediates of zwitterionic iodoniums in the reaction were isolated and verified by the X-ray crystallog. anal., which showcased unambiguous mechanistic insight into the reactivity of the reaction cascade. In the experiment, the researchers used many compounds, for example, potassium (3-bromophenyl)trifluoroborate(cas: 374564-34-8Electric Literature of C6H4BBrF3K)
potassium (3-bromophenyl)trifluoroborate(cas: 374564-34-8) belongs to organobromine compounds.The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. Electric Literature of C6H4BBrF3K Dehydrobromination, Grignard reactions, reductive coupling, Wittig reaction, and several nucleophilic substitution reactions are some of the principal reactions which involve organic bromides.
