4-Methoxyphenylacetylene, 98%, Thermo Scientific Chemicals

Description

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.
