How chemists create "SUPERBENZENE" (Kekulene) | Organic chemistry, synthesis & reaction mechanisms

Benzene is the classic example of aromatic stability with n=1 for the Hückel rule of 4*n 2. Big brain chemists also will know more exotic examples for aromaticity (e.g., the cyclopropyl cation). But have you heard of super-aromaticity? In this video, we will explore the classical (Staab, Diederich) and modern (Perez) synthesis of Kekulene.
