General procedure for the synthesis of trans-2-(4-tolyl)vinylboronic acid from 1-ethynyl-4-methylbenzene and catecholborane: 1-ethynyl-4-methylbenzene (0.50 mL, 3.94 mmol, 1.00 equiv) and catecholborane (0.50 mL, 4.73 mmol, 1.20 equiv) were dissolved in tetrahydrofuran (THF, 1.5 mL) , and the mixture was refluxed for 18 hours. After completion of the reaction, the solvent was removed by evaporation and water (1 mL) was added. The resulting suspension was stirred vigorously for 4 h at room temperature. The solid was collected by filtration and recrystallized with water. Subsequent filtration afforded (E)-2-(4-tolyl)vinylboronic acid (309.4 mg, 1.90 mmol, 48% yield) and dried under vacuum. The product was characterized by 1H NMR (400 MHz, DMSO-d6) and 13C NMR (101 MHz, DMSO-d6) with the following data: 1H NMR (DMSO-d6) δ 7.73 (s, 2H), 7.36 (d, J = 7.9 Hz, 2H), 7.18 (d, J = 7.9 Hz, 2H), 6.05 (d, J = 18.3 Hz, 1H), 2.31 (s, 3H); 13C NMR (DMSO-d6) δ 146.2, 138.4, 135.4, 129.8 (2C), 127.0 (2C), 21.3.
