title: Ancillary ligand-free copper catalysed hydrohydrazination of terminal alkynes with NH2NH2.
abstract: An efficient and selective Cu-catalysed hydrohydrazination of terminal alkynes with parent hydrazine is reported. The methodology tolerates a broad range of functional groups, allows for the synthesis of symmetrical and unsymmetrical azines, and can be extended to hydrazine derivatives and amines.
