CuBr2-promoted cyclization and bromination of arene-alkynes: C-Br bond formation via reductive elimination of Cu(III) species

A CuBr2-promoted cyclization and bromination of arene-alkyne substrates has been developed, affording 9-bromophenanthrene derivatives highly efficiently. This reaction provides a novel and efficient protocol for C-Br bond formation from an inorganic bromine source via the reductive elimination of th...
