A 2-to-2′ 18-to-18′ doubly linked Ni(ii) norcorrole dimer: an effectively conjugated antiaromatic dyad. Issue 50 (20th May 2020) - Liu, Si-Yu
Abstract : A fused norcorrole dimer has been synthesized in which each norcorrole unit exhibited distinct antiaromaticity. Abstract : The synthesis and properties of a 2-to-2′ 18-to-18′ doubly linked Ni(ii ) norcorrole dimer are described. It adopts a highly planar structure, resulting in effective electronic interactions between the constituent norcorrole units. Nevertheless, each norcorrole unit exhibits substantial antiaromaticity, which stands in sharp contrast to stacked norcorrole dimers.
