Abstract
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.
