Abstract
A series of phenylhydrazone derivatives was synthesized from arenediazonium tetrafluoroborates and active methylene compounds under high-speed ball milling. The reaction occurred in the absence of the solvent and products were obtained in good yield within short reaction times (no more than 30 min).
Keywords: Ball milling, solid-state synthesis, phenylhydrazones, arenediazonium tetrafluoroborates, active methylene compounds.
