In this video, I discuss various halogenating agents for alcohols and their mechanisms of reaction. Phosphorus tribromide and triiodide (PBr3 and PI3), as well as thionyl chloride (SOCl2), convert alcohols into their respective alkyl halides, without issues of rearrangement as found with halogen acids.

Alkyl sulfonates can also be used to synthesize alkyl halides and other compounds by capture of nucleophiles. They are isolable and can be formed under mild conditions, which is useful in synthetic organic chemistry.
