Abstract
Silver triflate was found to be an efficient catalyst for the cyclopropenation of internal alkynes using donor-/acceptor-substituted diazo compounds as carbenoid precursors. Highly substituted cyclopropenes, which cannot be synthesized directly via rhodium(II)-catalyzed carbenoid chemistry, can now be readily accessed.
摘要
三氟甲磺酸银被发现是一种有效的催化剂，可用于使用供体/受体取代的重氮化合物作为碳烯前体的内炔烃的环丙烷化反应。现在可以很容易地获得无法通过铑（II）催化的碳烯化学直接合成的高取代的环丙烷。
