as precusor, 2,7‐di(trimethylsilyl)‐thieno[3,2‐e]benzothiophene was obtained effiently via intramolecular McMurry reaction. At the same time, another two unexpected compounds, 1,2,5,6(5)‐tetra‐(trimethylsilyl)‐1,2,5,6(2,3)‐tetrathiophena‐cyclooctaphan‐3(Z),7(Z)‐diene and 2,7‐di(trimethylsilyl)thieno[3,2‐e]‐benzothiophene‐4‐ol were generated as side products. The crystal structures of all three title
以5,5'-二(三甲基硅烷基)-3,3'-联硫基苯基-2,2'-二甲醛为先驱物,通过分子内有效地获得了2,7-二(三甲基硅烷基)-噻吩并[3,2- e ]苯并噻吩麦克默里反应。同时,另外两个意外化合物1,2,5,6(5)-四-(三甲基甲硅烷基)-1,2,5,6(2,3)-四噻吩-环辛烷3(Z),7 (Z)-二烯和2,7-二(三甲基甲硅烷基)噻吩并[3,2 - e ]-苯并噻吩-4-醇是副产物。描述了所有三种标题化合物的晶体结构。
