PROCESS FOR THE PREPARATION OF CHLOROARYLACETYLENE PRECURSORS |
摘要 |
<p>Chloroarylacetylenes such as m-chlorophenylacetyl-ene and certain precursors to such chloroarylacetylene are prepared by reacting a chloroarylbromide with a substituted terminal acetylene compound containing at least three carbon atoms and a hydroxy group on the carbon atom adjacent to the acetylene group in the presence of a dialkyl or trialkyl amine solvent and a catalyst system consisting of a palladium complex containing two halogen moieties and two tri-substituted phosphine moieties. Additional triphenylphosphine can be added. A cuprous iodide promoter is also employed in the reaction sequence.</p> |
