Trimethyl 4,4',4''-(ethene-1,1,2-tri-yl)tribenzoate.

The title compound, C 26 H 22 O 6 , 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.
