Treatment of xanthates R-OC(S)SMe with (HF)9/Py and 1,3-dibromo-5,5-dimethylhydantoin gives trifluoromethyl ethers R-OCF3 through intermediates R-OCF2SMe, which could be isolated upon treatment of xanthates with n-Bu4N+H2F3− and N-bromosuccinimide.
用(HF)9 / Py和1,3-二溴-5,5-二甲基乙内酰脲处理黄药R-OC(S)SMe可以通过中间体R-OCF 2 SMe生成三氟甲基醚R-OCF 3,可以通过处理分离得到与黄原酸盐ñ -Bu 4 ñ + ħ 2 ˚F 3 -和ñ溴代琥珀酰亚胺。
