The Hückel rule defines that monocyclic and planar conjugated systems containing [4 + 2] π electrons are aromatic. Here, the authors highlight boron species that feature a globally 4 π system, defying the Hückel rule, but nonetheless exhibit aromaticity.
休克尔规则定义，含有[4 + 2]个π电子的单环平面共轭体系具有芳香性。在此，作者强调了具有全局4π体系的硼物种，它们虽违背休克尔规则，但仍表现出芳香性。
