CF3CH2I has been developed, demonstrating high efficiency, excellent functional‐group compatibility, especially with large sterically hindered groups. The key to success is the combination of nickel with readily available nitrogen and phosphine ligands. The powerful potential of this strategy is further demonstrated by the late‐stage modification of several derived bioactive molecules.

The rate of the reaction of sodiumsulfite with 1-(4-thiomethylphenyl)-2,2,2-trifluoroethyl bromide in 20% acetonitrile in water is kinetically zero-order in sulfite anion and at 0.27 M SO32− the reaction gives a 0.67:0.15:0.18 ratio of the C-1 sulfite adduct, the water adduct and the novel reduction product 1-(4-thiomethylphenyl)-2,2,2-trifluoroethane, respectively.
亚硫酸钠与1-(4-硫代甲基苯基)-2,2,2-三氟乙基溴在水中的20%乙腈中的反应速率在亚硫酸根阴离子中动力学为零级,在0.27 M SO 3 2-下反应得到C-1亚硫酸盐加合物,水加合物和新型还原产物1-(4-硫代甲基苯基)-2,2,2-三氟乙烷的比例分别为0.67:0.15:0.18。
