Beschreibung

4-Ethynylanisole was used in the synthesis of photo luminescent 1,2-dihydrophosphinines via a [4 + 2] cycloaddition. Along with an arylboronic acid and sodium azide in a copper-catalyzed, three-component synthesis of trisubstituted 1,2,4-triazoles. In a study of a gold (III)-catalyzed hydroamination of alkynes leading to N-vinylindoles3.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
