Formylation and diformylation of dithieno [2,3-b:3',2'-d] thiophene were prepared by two methods. Firstly, aromatic carbanions were prepared by 1 Br/Li exchange of bromo dithieno[2,3-b:3',2'-d]thiophene with n-BuLi in THF at low temperature; 2 deprotonation of dithieno[2,3-b:3',2'-d]thiophene with LDA.

二噻吩并[2，3-b：3'，2'-d]噻吩单醛与双醛的制备首先通过两种方法产生芳基负离子：1溴代并三噻吩在四氢呋喃中与正丁基锂发生的溴锂交换；2用LDA对二噻吩并[2，3-b：3'，2'-d]噻吩去质子化作用。
