Yield:42016-91-1 99.6%

Reaction Conditions:

with dichloro sulfoxide in dichloromethane at 55; for 2.5 h;Solvent;Temperature;Time;

Steps:

1-6

In a 250mL three-necked flask, add 30mmol of 3,5-diiodosalicylic acid, 0.3mmol of graphene oxide, dichloromethane, 90mmol of thionyl chloride, 3,5-diiodosalicylic acid and dichloromethane The mass ratio was 1:30, and the reaction was refluxed under heating and stirring at 55°C. After the reaction solution became clear, the reaction was continued for 2.5 hours, and the solvent was removed by rotary evaporation under reduced pressure. The final product was a yellow solid powder with a mass of 12.20 g.
