By using bis [ acetylacetonato ] copper as catalyst in solvent-free condition, 2,5-dibromo-3,4-bis ((octyloxy)-methyl)thieno[2,3-b]thiophene was prepared by the reaction of 2,5-dibromo-3,4-dimethylthieno[2, 3-b]thiophene with n-octyl alcohol. The factors which have an influence on the reaction were discussed and the optimum reaction condition was obtained.%以2,5-二溴-3,4-二甲基噻吩[2,3-b]并噻吩和正辛醇为原料,在二乙酰丙酮铜作催化剂和无溶剂条件下,合成了未见文献报道的产物2,5-二溴-3,4-二((辛氧基)甲基)噻吩[2,3-b]并噻吩,探讨了影响反应的各种因素,并找到了较好的合成条件.
