by lithiation of 2-bromo-3,3,3-trifluoroprop-1-ene and successively underwent borylation in a flow microreactor system. Direct use of the 1-(trifluoromethyl)vinylborate thus formed for the Suzuki–Miyaura coupling in a batch system afforded α-(trifluoromethyl)styrenes in high yields.
通过2-溴-3,3,3-三氟丙-1-烯的锂化生成热不稳定的(3,3,3-三氟丙-1-烯-2-基)锂,并在流动微反应器系统中依次进行硼化。直接将如此形成的1-(三氟甲基)乙烯基硼酸酯用于间歇系统中的Suzuki-Miyaura偶联,可提供高收率的α-(三氟甲基)苯乙烯。
