  • Publication number: 20160052863
    Abstract: There is provided a process for producing an aminopropyne or an enaminone comprising the step of reacting a metal acetylide, an amine and a carbonyl-containing compound in the presence of a transition metal catalyst. There is also provided a process for producing an aminopropyne comprising the step of reacting a metal acetylide, an amine and a halide-containing compound in the presence of a transition metal catalyst at a reaction temperature of 50° C. to 150° C. There are also provided processes to further synthesize the aminopropyne produced to obtain a butyneamine, another aminopropyne or a triazol.
    Type: Application
