title: A formal metal-free N-arylation via the Schmidt reaction of aromatic aldehydes with an azido amine.
abstract: A formal metal-free N-arylation of aromatic aldehydes with 3-azido-N-tosylpropan-1-amine through the Schmidt process was realized in the presence of acids. TfOH was found to be a good promoter, and the exclusive 1,2-aryl migration was observed. Furthermore, the conversion of an aliphatic aldehyde to the N,N-disubstituted formamide was achieved in excellent yield.
