WebSep 20, 2024 · Electrophilic aromatic substitution (EAS) reactions are widely regarded as characteristic reactions of aromatic species, but no comparable reaction has been reported for molecules with Craig-Möbius aromaticity. Here, we demonstrate successful EAS reactions of Craig-Möbius aromatics, osmapentalenes, and fused osmapentalenes. WebThe EAS mechanism is shown here, in this synthesis of the dye Methyl Red from 2-aminobenzoic acid and N, N -dimethylaniline: In another example, Para Red is synthesized from 2-naphthol and 4-nitrobenzenediazonium hydrogen sulfate: Contributors Martin A.
