Synthesis
4-tert-butylbromobenzene was used as starting material and 4-tert-butylphenylboronic acid (4b) was synthesized according to the method described in literature [22] in 72.8% reaction yield. The resulting product was a white solid with a melting point of 158-160 °C (literature value: 160 °C). The structure of the product was confirmed by 1H NMR spectrum (CD3Cl as solvent, 300 MHz): δ 8.17 (d, 2H, J = 6.6 Hz), 7.42-7.54 (m, 2H), 1.38 (s, 9H).
