Electric Literature of 141305-40-0, An article , which mentions 141305-40-0, molecular formula is C9H6BrNS. The compound – 4-Bromo-2-phenylthiazole played an important role in people’s production and life.
A family of 6-hydroxypicolinamide ligands have been identified as effective supporting ligands for Cu-catalyzed couplings of heteroaryl bromides and chlorides with heteroaryl primary amines. The C-N couplings are carried out at 80-120 C in DMSO or sulfolane using K2CO3 or K3PO4 as the base with 2-10 mol % CuI and supporting ligand. The strength of the base was found to have an impact on the chemoselectivity and rate. The use of K2CO3 as the base enabled selective C-N coupling of aryl bromides over aryl chlorides with 2-5 mol % Cu at 80-120 C. With K3PO4 as the base, aryl chlorides are capable of undergoing C-N coupling, though 5-10 mol % Cu is required at 120-130 C. Members of the ligand family are straightforward to prepare in one step from 6-hydroxypicolinic acid and the corresponding anilines.
