Abstract:Singly‐linked aromatic [22]smaragdyrin BF2 complex dimer was synthesized by the reductive coupling of 16‐brominated [22]smaragdyrin BF2 complex, which was oxidized to a stable diradical with PbO2. As the first example of fused smaragdyrin dimer, a fused [22]smaragdyrin BF2 complex dimer was synthesized by the oxidation of a CuCl‐BF2 complex dimer with FeCl3 and subsequent reduction with NaBH4. After removal of the BF2 group, the singly‐linked and fused aromatic dimers were oxidized to the corresponding antiaro… Show more
