本研究发现电石（CaC2）与N -（三甲基硅基）咪唑（TMSIm）在二氯甲烷中以CuBr为催化剂直接反应可合成双（三甲基硅基）乙炔（BTMSA），且反应温度为100℃。对照实验表明，该反应不经乙炔途径进行。据我们所知，这是首次在温和条件下用cac2和硅基化试剂直接反应合成BTMSA。
In this work, we discovered that bis(trimethylsilyl)acetylene (BTMSA) could be synthesized by the reaction of calcium carbide (CaC2) 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 CaC2and a silylation reagent under mild conditions.
