Hydrodehalogenation is a straightforward approach to detoxifying harmful organohalides, in which the halogen atom is formally substituted with a hydrogen atom. Herein, a catalytic system using Cp₂TiCl₂ as the catalyst and ammonia–borane as the reductant is described. A series of benzyl halides and inactivated alkyl halides (including alkyl chlorides) readily reacted to give the corresponding hydrodehalogenated products in yields of up to 97% (43 examples).
