Microwave-enhanced aromatic dehalogenation studies: a rapid deuterium-labelling procedure

Rapid (<1 min) and specific deuterium labelling is achieved through the microwave-enhanced dehalogenation of a number of N-4-picolyl-4-halogenobenzamides using deuterated formate as solid deuterium donor and either homogeneous or heterogeneous catalysts; the percentage deuterium incorporation is a function of the kind of solvent used.
