摘要
3,3'-二溴二苯乙炔与β-噻吩频哪醇硼酸酯发生Suzuki偶联反应制得3,3'-二(2,5-二十二烷基-3-噻吩)二苯乙炔(7);Co2(CO)8催化7自身环三聚合成了新型六[间-(β-噻吩基)苯基]苯衍生物——六{3-[2',5'-二(十二烷基)-3-噻吩]苯基}苯,产率86%,其结构经1H NMR和MS表征。
3,3′-Bis（2,5-didodecylthiophen-3-yl）diphenyl acetylene（7） was prepared by Suzuki coupling reaction of 3,3′-dibromo-diphenyl acetylene with β-thiophene boronic acid pinacol ester.A novel hexakis[m-（β-thienyl）phenyl]benzene derivative,hexa{3-[2′,5′-didodecylthiophen-3-yl]phenyl}benzene,was synthesized by cyclotrimerization of 7 self catalyted by Co2（CO）8 in yield of 86%.The structure was characterized by 1H NMR and MS.
