Deuterated compounds are of great importance in chemistry and pharmaceuticals. Reductive
dehalogenation is one of the most useful methods to incorporate deuterium into molecules.
This article briefly discusses the historical development of dehalogenative deuteration
reactions that involve transition-metal catalysis, radical halogen abstraction, alkali-metal
reductive deuteration, and the recently developed potassium methoxide/hexamethyldisilane-mediated
dehalogenation of aryl halides.
Key words
deuteration - dehalogenation - aryl halides - Transition-metal-free - potassium base
