Deiodinative fluorination of alkyl iodide with p-iodotoluene difluoride
Oxidative fluorination of alkyl iodides with p-iodotoluene difluoride (4) was carried out. In the presence of Et3N-4HF, the fluorination reaction of prim-alkyl iodides selectively took place at the iodine position under mild conditions to give the corresponding alkyl fluorides in good yields.
