Synthesize 2,5-Dibromo-3,4-bis((octyloxy)Methyl)ThienoThiophene by Using bis[Acetylacetonato]Copper as Catalyst in Solvent-Free Condition

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.

By using bis[acetylacetonato]copper as catalyst in solvent-free condition,2,5-dibromo-3,4-bis（（octyloxy）-methyl）thienothiophene was prepared by the reaction of 2,5-dibromo-3,4-dimethylthienothiophene with n-octyl alcohol.The factors which have an influence on the reaction were discussed and the optimum reaction condition was obtained.
