摘　　要：噻吩及其衍生物因其独特的结构和光电性能广受关注.本文中以2,5-二甲基噻吩为原料,通过卤代、与正丁基试剂反应合成噻吩双锂试剂,再与二苯基氯化膦发生亲核取代反应合成目标化合物3,4-二(二苯基膦基)-2,5-二甲基噻吩.采用核磁共振(~1H、^(13)C、^(31)P NMR)、傅里叶变换红外光谱(FT-IR)、液质联用飞行时间质谱(LC-MS-TOF)等对目标化合物进行表征,确证了结构,为后续合成金属配合物发光材料提供了前体.该化合物目前鲜见报道.Thiophene and its derivatives have attracted more and more interests due to their unique structure and properties.2,5-dimethylthiophene was used as starting material,by halogenation and reacted with n-butyllithium,thiopheneyldilithium reagent was obtained and further reacted with chlorodiphenylphosphine,the title compound 3,4-bis(diphenylphosphino)-2,5-dimethylthiophene was synthesized.The structure of the title compound was characterized and confirmed by NMR(1 H、13 C and 31 P NMR)、FT-IR、LC-MS-TOF spectra.It provided a precursor for synthesis of luminescent metal complexes in the further step.As far as we know,this compound has been rarely reported.
