YieldReaction ConditionsOperation in experiment
81% With tetrakis(triphenylphosphine) palladium(0); tetrabutylammomium bromide; caesium carbonate; In water; toluene; for 24.0h;Inert atmosphere; 5-Bromoisophthalaldehyde (1) and diformylphenylboronic ester (2)were prepared according to the previously reported procedure [23].Bromotriphenylethylene (1.34 g, 4.0 mmol), 2 (1.28 g, 4.8 mmol), tetrabutylammoniumbromide (0.03 g, 0.1 mmol) and Cs2CO3 (1.30 g, 4.0mmol) were dissolved in the mixture of toluene (40 mL) and H2O (5 mL).The reaction mixture was degassed and stirred under nitrogen atmospherefor 0.5 h, and then a catalytic amount of Pd(PPh3)4 (0.11 g, 0.1mmol) was added and refluxed for another 24 h. After being cooled toroom temperature, the solvent was removed under a vacuum. The crudeproduct was purified by column chromatography to get pale powder ofTPE-2CHO with a yield of 1.25 g (81%). 1H NMR (400 MHz, CDCl3): δ9.87 (s, 2H), 8.10 (t, J = 1.52 Hz, 1H), 7.78 (d, J = 1.56 Hz, 2H),7.17-7.09 (m, 9H), 7.05-7.00 (m, 6H). 13C NMR (100 MHz, CDCl3): δ191.0, 146.2, 143.8, 142.5, 142.4, 142.1, 138.2, 137.6, 136.6, 131.3,131.2, 131.0, 128.2, 128.2, 128.1, 127.8, 127.3, 127.2, 127.1.

Calculated for C28H20O2: C, 86.56; H, 5.15%. Found: C, 86.47; H,5.34%. Single crystals suitable for X-ray diffraction measurements wereobtained in CH2Cl2 for a week.
