The synthesis of alkyl fluorides is best accomplished by
free radical fluorination
Sandmeyer's reaction
Finkelstein reaction
Finkelstein reaction
D.
Finkelstein reaction
Alkyl fluorides can be prepared by the action of mercurous fluorides or antimony trifluoride (inoragnic fluorides) on corresponding alkyl halide.
This reaction is known as Swarts reaction
CH3Br + AgF → CH3F + AgBr
But, when the action of NaI/acetone takes place on alkyl chloride or bromide alkyl iodide forms. This reaction is called 'Finkelstein reaction.
Free radical fluoridation is a highly explosive reaction. So not preferred for the preparation of fluoride.
