Ma, Xinyuan published the artcileAzolium Aurates as Pre-Catalysts for the Oxidative Coupling of Terminal Alkynes under Mild Conditions, Category: imidazoles-derivatives, the publication is Journal of Organic Chemistry (2022), 87(7), 4883-4893, database is CAplus and MEDLINE.
A simple and efficient method for the oxidative coupling of terminal alkynes was reported for the first time, using imidazol(in)ium aurates as pre-catalysts. This approach displayed high functional group tolerance and led to a broad range of 1,3-diyne compounds in moderate to excellent yields using low catalyst loading and was performed in air under mild and sustainable conditions.
