The synthesis of alkyl fluorides is best accomplished by:

Accepted Answer

Alkyl fluorides are more conveniently prepared by heating suitable chloro

-

or bromo-alkanes with organic fluorides such as

As{F_3},\,\,Sb{F_3},\,\,Co{F_2},\,\,AgF,\,H{g_2}{F_2}\,\,

etc.

This reaction is called Swarts reaction.

C H_{3} B r + A g F \overset{}{⟶} C H_{3} F + A g B r

2 C H_{3} C H_{2} C l + H g_{2} F_{2} \overset{}{⟶}

\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,2C{H_3}C{H_2}F + H{g_2}Cl{}_2
