The rate of the reaction of sodium sulfite 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。
