Abstract

The possible aromatic conjugation between 3D and 2Daromatic units is in the focus since the synthesis of benzocar-borane. It has been showed that in the 3D aromatic icosahedral1,2-dicarba-closo-dodecaborane systems fused with 2D aromaticrings a global 3D/2D aromaticity does not exist. Despite thisfact during the last years several studies proposed interactionsbetween 2D and 3D moieties. Herein, while tuning the size andthe effective charge of the (car)borane systems, we demon-strate that global aromatic character can be excluded in anyinvestigated cases, and the detectable conjugative propertiescan be explained the effect of the well-known negative hyper-conjugation.
