[(2,2'-bipyridine)Cu(trifluoromethylselenolate)]2 (also named as [(2,2'-bipyridine)Cu(SeCF3)]2, [(bpy)CuSeCF3]2) is one member of the family ofcopper(I) trifluoromethylselenolate reagents developped by Weng group. It was recently reported to be air-stable and highly efficient for nucleophilic trifluoromethylselenolation of a broad range of substrates, such as (hetero)aryl halides, alkyl halides, α-Halo-α,β-unsaturated carbonyl compounds, propargylic chlorides, allylic bromides, seleno-α,β-unsaturated ketones, vinyl halides, acid chlorides, 3- or 4-iodo(bromo)-2-pyrones and α-bromoketones, etc.
