Yield:-

Reaction Conditions:

with α,α,α-trifluorotoluene;sodium iodide in acetone at 50; for 72 h;

Steps:

1.1
Take 1000mL of three bottles, add acetone 600mL, And then into the three bottles of CH2FCl gas,Approximately 2.5 hours of ventilation.Then take 1mL of acetone solution,Add 100 μL of trifluoro toluene solution as internal standard,The solution contains about 1.26 mol of CH2FCl,Then NaI (1.50 mol, 225 g, 1.0 equiv) was weighed into the system,Equipped with reflux condenser,The reaction was carried out at 50 ° C for three days.After the reaction,Take a 2000mL separatory funnel,Add 1000 mL of water,The acetone solution slowly added to the funnel, the solution layer, after joining,Solution layer, take the next layer of brown liquid, add saturated Na2SO3 solution washing,And then washed three times with water to give colorless transparent liquid 12mL (containing a small amount of water and acetone), directly for the next step, without further purification.
