✦ Synopsis
surmnary: TricarbonylcycZohexudienyZiwniron sdts are synthetGaZZy equivaZent to specifieuZZy suhtituted phenyE cationa. More extensive ability to form carbon-carbon bonds with aromatic rings would enlarge the scope of useful synthetic methods.1 Nucleophilic substitution of aryl halides by carbon nucleophiles requires the presence of o-and/or p-substituents with electron withdrawing character (e.g. N02),
