In this work, we discovered that bis(trimethylsilyl)acetylene (BTMSA) could be synthesized by the reaction of calcium carbide (CaC 2 ) directly with N‐(trimethylsilyl)imidazole (TMSIm) in dichloromethane using CuBr as the catalyst, and reaction could occur efficiently at 100 °C. Control experiment indicated that the reaction did not proceed via acetylene pathway. As far as we know, this is the first work for BTMSA synthesis by direct reaction of CaC 2 and a silylation reagent under mild conditions.
