Triarylboranes have gained substantial attention as catalysts for C-C bond forming reactions due to their remarkable catalytic activities. Herein, we report B(CF) catalysed cyclopropenation of a wide variety of arylacetylenes using donor-acceptor diazoesters. A mild reaction protocol has been developed for the synthesis of functionalised cyclopropenes (33 examples) in good to excellent yields.
由于其卓越的催化活性，三芳基硼烷作为碳-碳键形成反应的催化剂已受到广泛关注。在此，我们报道了使用给体-受体重氮酯，B(CF)催化多种芳基乙炔的环丙烷化反应。已开发出一种温和的反应方案，用于以良好至优异的产率合成功能化环丙烯（33个实例）。
