One-pot halogen dance/Negishi cross-coupling of readily available 2,5-dibromothiophenes is described. A lithium diisopropylamide (LDA)-mediated halogen dance reaction resulted in the formation of thermodynamically stable α-lithiodibromothiophenes, which w

Brominated anthraquinones can be synthesized directly from bromothiophenes when these are reacted with 1,4-naphthoquinones in the presence of meta-chloroperoxybenzoic acid. The bromoanthraquinones are versatile building blocks in the preparation of arylated anthraquinones and of extended π-systems with interspersed anthraquinone units.
