Abstract
A process for preparing N-alkyl-substituted aminoalkynes by reacting an alkyne with a carbonyl compound and an amine with heterogeneous catalysis in which an unsupported copper acetylide derived from malachite is used as the catalyst. The N-alkyl-substituted aminoalkyne have a wide variety of uses including their use as precursors for pharmaceuticals, their use in electroplating processes and their use as corrosion inhibitors.
