with the Ruppert-Prakash reagent and, after desilylation of the intermediate adduct, gave the corresponding tertiary 2,2,2-trifluoroethanols. Similarly, ferrocenyl carbaldehyde was converted into 1-ferrocenyl-2,2,2-trifluoroethanol via nucleophilic trifluoromethylation. Some of the obtained fluorinated alcohols were transformed into thiols by treatment with Lawesson’s reagent or P2S5·2C5H5N complex.
二茂铁基和杂芳基取代的酮与Ruppert-Prakash试剂平稳反应,并且在中间加合物甲硅烷基化后,得到相应的叔2,2,2-三氟乙醇。类似地,二茂铁基甲醛通过亲核三氟甲基化转化为1-二茂铁基-2,2,2-三氟乙醇。通过使用Lawesson试剂或P 2 S 5 ·2C 5 H 5 N络合物处理,将所得的某些氟化醇转化为硫醇。显着地,所获得的硫醇是无味的化合物。
