Page/Page column 28, (2013/03/26)
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.

AHA Erlebnis: CaC2, used to produce acetylene until several decades ago, is re-emerging as a cheap, sustainable resource synthesized from coal and lignocellulosic biomass. We report efficient catalytic protocols for the synthesis of functional acetylene derivatives from CaC2 through aldehyde, alkyne, and amine (AAA) as well as alkyne, haloalkane, and amine (AHA) couplings, and in addition demonstrate its use in click and Sonogashira chemistry, showing that calcium carbide is a sustainable and cost-efficient carbon source.
