Ullmann-like reductive coupling of 1,4-diiodo-2,3,5,6-tetrafluorobenzene, promoted by copper(I) thiophene-2-carboxylate in N-methylpyrrolidinone at room temperature, followed by treatment with lithium aluminum hydride in THF, allowed us to obtain fluorinated poly(para-phenylene) oligomers containing up to five aromatic rings with hydrogen atoms as terminal groups.
在室温下,由N-甲基吡咯烷酮中的噻吩-2-羧酸铜(I)促进Ullmann样的1,4-二碘-2,3,5,6-四氟苯的还原偶联,然后在THF中用氢化铝锂处理,使我们能够获得含多达五个以氢原子为末端基团的芳环的氟化聚(对亚苯基)低聚物。
