A careful methodological study revealed a true Click catalytic system based on commercially available [CuBr(PPh(3))(3)]. This system is active at room temperature, with 0.5 mol % [Cu] (or less), in the absence of any additive, and it does not require any purification step to isolate pure triazoles.
一项细致的方法学研究揭示了一种真正的点击催化体系,该体系基于市售的[CuBr(PPh3)3]。该体系在室温下具有活性,[Cu]的用量为 0.5mol%(或更少),无需任何添加剂,也不需要任何纯化步骤即可分离得到纯三唑产物。
