On December 29, 2021, Kang, Kai; Loud, Nathan L.; DiBenedetto, Tarah A.; Weix, Daniel J. published an article.SDS of cas: 574-98-1 The title of the article was A General, Multimetallic Cross-Ullmann Biheteroaryl Synthesis from Heteroaryl Halides and Heteroaryl Triflates. And the article contained the following:
A new, general approach to biheteroaryls: the Ni- and Pd-catalyzed multimetallic cross-Ullmann coupling of heteroaryl halides with triflates. An array of 5-membered, 6-membered and fused heteroaryl bromides and chlorides, as well as aryl triflates derived from heterocyclic phenols proved to be viable substrates in this reaction (62 examples, 63 ± 17% average yield). The generality of this approach to biheteroaryls were further demonstrated in 96-well plate format at 10μmol scale. An array of 96 possible products provided >90% hit rate under a single set of conditions. Further, low-yielding combinations was rapidly optimized with a single “Toolbox Plate” of ligands, additives and reductants. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).SDS of cas: 574-98-1
