Trimethyl 4,4′,4′′-(ethene-1,1,2-triyl)tribenzoate

Abstract

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