Beschreibung

Allgemeine Beschreibung

Phenylacetylene is an aromatic organic compound frequently employed in Sonogashira coupling reactions. Phenylacetylene undergoes polymerization catalyzed by Rh and Pt complexes to form polyphenylacetylene.

Anwendung

Terminal acetylene used in the conversion of nitrones to alkynyl hydroxyl amines in the presence of trimethylaluminum..

Phenylacetylene was used in a study to investigate the mechanism of product formation during the palladium-catalysed phenylacetylene oxidative carbonylation reaction.
