electron-withdrawing functionality has been implemented. The catalytic manifold operates under the reactivity generation principle "a good nucleophile generates a strong base", and it uses 1,4-diazabicyclo[2.2.2]octane (DABCO) as the catalyst, activated terminal alkynes as substrates and acetone cyanohydrin as the cyanide source. The acrylonitriles obtained as E,Z mixtures are straightforwardly resolved by simple flash
                                    已经实现了通用的,实用的和可扩展的有机催化氢
氰化歧管,以提供具有吸电子功能的β-取代的
丙烯腈。催化歧管按照反应活性生成原理“良好的亲核试剂生成强碱”操作,它使用1,4-二氮杂
双环[2.2.2]辛烷(
DABCO)作为催化剂,活化的末端
炔烃作为底物,
丙酮氰醇作为催化剂。
氰化物来源。通过简单的快速色谱法可直接拆分作为E,Z混合物获得的
丙烯腈,以制备量提供纯净的异构体。
