Direct Exploitation of the Ethynyl Moiety in Calcium ...

May 29, 2020  Ball milling of calcium carbide (CaC 2) enables the reaction of its ethynyl moiety with organic electrophiles. This was realized simply by co‐milling CaC 2 with organic substrates in a sealed jar without the need for an additive or a catalyst. Various ketones including those bearing α‐hydrogens were ethynylated in good yields at short reaction times.

Calcium carbide (CaC2) is widely used for the production of various acetylene derivatives, accompanying with a huge amount of carbide slag waste. To develop a clean production process, we explored the reaction of CaC2 and glycerol at varying conditions for the first time. The products were characterized by various techniques. It is observed that CaC2 can react with glycerol at ambient ...
