A series of new carboranyl organosilicon monomers have the potential to be used as high temperature oils, as building blocks in sol-gel processes and as an additive in composites. The versatile and easy preparation of the four polyhedral carboranyl derivatives are based on UV initiated hydrothiolation. The compounds were isolated in good yields (65–95%) and characterized by ¹H, ¹¹B, ¹³C and ²⁹Si NMR, IR spectroscopy, HRMS ESI and elemental microanalysis. Assignment of ¹H and ¹³C NMR spectra was made on the basis of 2D experiments of COSY, HMQC and HMBC.

合成新的碳硼烷基有机硅衍生物–制备杂化有机无机材料的前体

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。
