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.

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 …
