good yields under free radical conditions. Reduction of the resulting secondary iodides gave long-chain alkanethioacetates with perfluoroalkyl terminal segments. These intermediates were readily transformed into the corresponding terminally perfluorinated alkanethiols by acidic deprotection. The product thiols should find use in the generation of well-defined fluorinated interfaces using the self-assembled
本文描述了一系列含全氟化末端链段的链烷硫醇的合成:F(CF 2)m(CH 2)n SH,其中m = 1,n = 9-15;m = 2,n = 11-14;m = 3,n = 10-13;和米 = 4,Ñ = 9-12。通式F(CF 2)m(CH 2)n I的氟化烷基碘,其中m = 1-4和n 将= 0或1添加到在α末端被硫代乙酸酯基官能化的长链ω-烯烃。反应在自由基条件下以良好的产率进行。所得仲碘的还原得到具有全氟烷基末端链段的长链链烷硫基乙酸酯。这些中间体很容易通过酸性脱保护作用转化为相应的末端全氟链烷硫醇。使用自组装单分子层(SAM)技术,应将产物硫醇用于定义明确的氟化界面。
