3-Substituted benzotrifluorides are selectively deprotonated and functionalized in the 2-position. The selectivity is achieved by equilibrating the mixture of lithiobenzotrifluorides initially formed in the presence of a primary or secondary amine catalyst.
3-取代苯三氟化物在2-位选择性去质子化和官能化。该选择性是通过在一级或二级胺催化剂的存在下平衡最初形成的锂苯三氟化物混合物来实现的。
