were synthesized employing Sonogashira cross-coupling conditions. All three molecules underwent facile di- or trimetalation with potassium tert-butoxide to afford the respective oligosilyldi- and trianions.
在Sonogashira交叉偶联条件下合成了1,3-和1,4-双[三(三甲基硅烷基)甲硅烷基乙炔基]苯以及1,3,5-三[三(三甲基硅烷基)甲硅烷基乙炔基]苯。所有三个分子都用叔丁醇钾进行了简单的二金属化或三金属化,以得到各自的低聚甲硅烷基二和三阴离子。
