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.

Abstract

10,10′-dibromo-9,9′-bianthracene undergoes efficient Heck coupling with a series of para-substituted styrenes in the presence of a simple palladium-based catalytic system. The reaction proceeds with complete regio- and stereoselectivity. The disadvantage of this method is the minor competitive catalytic hydrodebromination.
