以2，3，4，5-四溴噻吩和二甲基氯硅烷为原料，在镁和催化量的氰化铜（I）存在下合成了2，3，4，5-四（二甲基硅基）噻吩（1）。分子轨道计算和紫外光谱研究表明，1的二甲基硅基对噻吩环的结构和电子性质有很大的影响。
2,3,4,5-Tetrakis(dimethylsilyl)thiophene (1), the first 2,3,4,5-tetrasilylthiophene, was synthesized by the reaction of 2,3,4,5-tetrabromothiophene with chlorodimethylsilane in the presence of magnesium and a catalytic amount of copper(I) cyanide. The dimethylsilyl groups of 1 considerably affect the structure and the electronic properties of the thiophene ring, which was revealed by molecular orbital calculations and UV spectroscopy.
