Heck Coupling of 10,10′-Dibromo-9,9′-bianthracene with Para-Substituted Styrenes—Evaluation of the Reaction as a Method for Synthesising Polyunsaturated Bianthracene Derivatives

Key Points

• The central aim is to evaluate the Heck coupling of dibromo-bianthracene with various para-substituted styrenes.
• Utilized a palladium-based catalytic system for the coupling reaction.
• Examined multiple para-substituted styrenes as reactants.
• Assessed regio- and stereoselectivity of the reaction.
• Achieved complete regioselectivity in the coupling process.
• Noted stereoselectivity under the reaction conditions.
• Identified minor competitive catalytic hydrodebromination as a drawback.
