Oxidative Addition Complexes as Precatalysts for Cross-Coupling Reactions Requiring Extremely Bulky Biarylphosphine Ligands was written by Ingoglia, Bryan T.;Buchwald, Stephen L.. And the article was included in Organic Letters in 2017.Category: quinoxaline This article mentions the following:
Palladium-based oxidative addition complexes derived from aryl triflates or bromides and the bulky phosphine ligands AlPhos and t-BuBrettPhos were prepared as easily prepared, air-stable, and effective precatalysts for C-N, C-O, and C-F cross-coupling reactions with a variety of (hetero)arenes. These complexes offer a convenient alternative to previously developed classes of precatalysts, particularly in the case of the bulkiest biarylphosphine ligands, for which palladacycle-based precatalysts do not readily form. The structure of an AlPhos (trifluoromethylphenyl)palladium triflate complex benzene solvate was determined by X-ray crystallog. In the experiment, the researchers used many compounds, for example, 6-Chloroquinoxaline (cas: 5448-43-1Category: quinoxaline).
6-Chloroquinoxaline (cas: 5448-43-1) belongs to quinoxaline derivatives. Quinoxaline is isomeric with other naphthyridines including quinazoline, phthalazine and cinnoline. Modifying quinoxaline structure it is possible to obtain a wide variety of biomedical applications, namely antimicrobial activities and chronic and metabolic diseases treatment.Category: quinoxaline
