Abstract

The title compound, C₂₆H₂₂O₆, is formed as the major product from the reaction between syn-1,2-bis-(pinacolatoboron)-1,2-bis-(4-methyl-carb-oxy-phen-yl)ethene and excess methyl 4-iodo-benzoate in basic DMSO using a palladium catalyst at 80°C via Suzuki coupling followed by protodeboronation. Crystals were grown by slow evaporation of a hexa-nes solution at room temperature.

Keywords: Suzuki coupling; crystal structure; protodeboronation.
