Solvent-free ruthenium-catalysed vinylcarbamate synthesis from phenylacetylene and diethylamine in ‘supercritical’ carbon dioxide
Abstract
The solvent-free synthesis of β-[(diethylcarbamoyl)oxy]styrene from phenylacetylene and diethylamine in supercritical carbon dioxide is greatly accelerated for a series of ruthenium catalysts compared to the same reactions in toluene.
