A practical and scalable single electron transfer reduction enables the reduction and reductive deuteration of tertiary amides in the presence of sodium dispersions. The chemoselectivity of this method highly depends on the nature of the proton donor. Whereas the combination of Na/EtOH affords alcohol products, the use of Na/NaOH/H2O leads to the formation of amines.
