twin-chain hydroxyalkylthiols (mercaptoalkanols) featuring a nearly constant cross-section and the potential for modification of one or both termini are available with complete regioselectivity through Pd-mediated couplings of benzene diiododitriflate, including an example of a previously unreported coupling to generate an ortho-substituted arene bis acetic acid. Self-assembled monolayers (SAMs) prepared from
通过Pd介导的二碘二三氟甲磺酸苯偶合偶合,具有完全区域选择性的新型新型双链羟烷基硫醇(巯基链烷醇)具有近乎恒定的横截面和修饰一个或两个末端的潜力,包括以前未报道的偶合的一个例子生成邻位取代的芳烃双乙酸。与由类似的单链硫醇制备的单分子膜相比,由新型两亲化合物制备的自组装单分子膜(SAM)在电化学传感器系统中表现出更高的稳定性。
