Piou, Tiffany published the artcileDirect Arylation of Azoles Enabled by Pd/Cu Dual Catalysis, SDS of cas: 25753-84-8, the publication is Organic Letters (2021), 23(6), 1996-2001, database is CAplus and MEDLINE.
A practical approach toward the synthesis of 2-arylazoles via direct arylation was described. The transformation relied on a Pd/Cu cocatalyst system that operated with low catalyst loadings. The reaction conditions were found to be tolerant of a wide range of functional groups and nitrogen-containing heterocycles commonly employed in a drug discovery setting.
