Abstract: 2,2’,7,7’-tetraiodo 9,9’-spirobifluorene (2) is the key intermediate of hole transport media and conducting polymers. We developed a practical method by which 2 was highly selective synthesized in good yield.

Key words: 2,2’,7,7-’tetraiodo-9,9’-spirobifluorene, sprain compound, Sandmeyer reaction
