In the Swarts reaction, **cobalt(III) fluoride (CoF₃)** is used as a fluorinating agent. Cobalt(III) fluoride is effective in facilitating the substitution of halogens (like Cl or Br) with fluorine in organic compounds. Cobalt(II) fluoride (CoF₂) is a different compound and is not typically used in the Swarts reaction. So, the correct and commonly used compound for the Swarts reaction is **cobalt(III) fluoride (CoF₃)**. And For the Swarts reaction, **mercury(I) fluoride (Hg₂F₂)** is the standard and commonly used fluorinating agent. This is because it effectively facilitates the substitution of halides (like Cl or Br) with fluorine in organic compounds. While **mercury(II) fluoride (HgF₂)** is a different compound and also a source of fluorine, it is not typically used in the Swarts reaction. The specific reactivity and mechanisms required for the Swarts reaction are best met by Hg₂F₂. So, to follow the standard procedure and achieve the best results in the Swarts reaction, you should use **mercury(I) fluoride (Hg₂F₂)**. Source : Chat gpt
