carboxylates with (trifluoromethyl)trimethylsilane (Me3SiCF3) that results in the formation of O-silyl-protected 2-aryl-1,1,1,3,3,3-hexafluoroisopropanols is reported. A phenoxide anion, generated during the trifluoromethylation of the phenyl carboxylate, also activates the Me3SiCF3, which permits a catalytic amount of the fluoride anion source to be used. Various functional groups, which can be used for further
苯基芳香族羧酸盐与(三氟甲基)三甲基硅烷(Me 3 SiCF 3)的氟阴离子引发的反应是形成O-甲硅烷基保护的2-芳基-1,1,1,1,3,3,3-六氟异丙醇报告。在苯基羧酸酯的三氟甲基化过程中产生的酚盐阴离子也会活化Me 3 SiCF 3,从而允许使用催化量的氟化物阴离子源。在反应中可以容忍可用于进一步修饰的各种官能团。
