Reaction Steps

ICl (1.0 M in methylene chloride, 2.80 ml, 2.80 mmol) is added dropwise to a solution of 2-trimethylsilyl-9,9-bis(2-methylbutyl)-9′,9′,9″,9″-tetrakis(n-propyl)-7,2′;7′,2″-terfluorene (13a) (2.45 g, 2.80 mmol) in CCl4 (15 ml) at 0° C. After stirring for 30 min, the reaction mixture is poured into a Na2CO3 aqueous solution (5 wt %) with vigorous stirring until discoloration for extraction with methylene chloride. The organic extracts are washed with brine before dried over MgSO4. Upon evaporating off the solvent, the residue is washed with ethanol to yield 2-iodo-9,9-bis(2-methylbutyl)-9′,9′,9″,9″-tetrakis(n-propyl)-7,2′;7′,2″-terfluorene (14a) (2.36 g, 91%) as a light yellow solid.
