一系列新型碳硼烷基有机硅单体有潜力用作高温油,用作溶胶-凝胶工艺的基础材料以及用作复合材料的添加剂。四种多面体碳硼烷基衍生物的通用性和简便制备是基于UV引发的氢硫醇化作用。分离出的化合物收率很高(65–95%),并通过1 H,11 B,13 C和29 Si NMR,IR光谱,HRMS ESI和元素微量分析进行了表征。基于COSY,HMQC和HMBC的二维实验,确定了1 H和13 C NMR光谱。
AbstractA novel route for synthesis of B‐mercaptocarboranes is described. The reaction proceeds through Pd‐catalyzed iodine exchange with the sulfur nucleophile TIPS–SH in mono‐ and diiodinated ortho‐, meta‐, and para‐carboranes. Self‐assembled monolayers of selected B‐mercaptocarboranes on a gold surface were analyzed by X‐ray photoelectron spectroscopy and their water contact angles were assessed.
