The Suzuki–Miyaura reaction of 1,4-dibromo-2-fluorobenzene with two equivalents of arylboronic acids gave fluorinated para-terphenyls. The reaction with 1 equiv of arylboronic acid resulted in site-selective formation of biphenyls. The one-pot reaction of 1,4-dibromo-2-fluorobenzene with two different arylboronic acids afforded fluorinated para-terphenyls containing two different terminal aryl groups
1,4-二溴-2-氟苯与两当量的芳基硼酸的Suzuki-Miyaura反应产生了氟化的对三联苯。与1当量的芳基硼酸的反应导致联苯的位点选择性形成。1,4-二溴-2-氟苯与两种不同的芳基硼酸的一锅法反应得到含两个不同的末端芳基的氟化对-三联苯。
